UPDATED: COVID-19 Vaccine and Therapeutic Development Tracker

The latest coronavirus updates and developments impacting the global pharmaceutical supply chain. Includes the latest news surrounding the therapeutic developments, updates to vaccines and boosters, and the global pharmaceutical regulations that need to be met. 

16 October 2024

Novavax's latest clinical trial for NVAX.O., the combination COVID-influenza shot, has been put on hold by the US FDA after adverse effects were reported by a participant who had received the vaccine in January last year. The trial is paused while the company is working with the FDA to determine whether the event was caused by the vaccine, and whether they can continue onwards with a Phase III trial. 

23 August 2024

Moderna and Pfizer-BioNTech both receive approval under the FDA's emergency use authorisation for their updated COVID-19 vaccines. The vaccines, Comirnaty and Spikevax, both mRNA vaccines were recently updated in an effort to defend against the circulating KP.2 variant of Omicron. The vaccines have been developed to protect against severe outcomes of the virus. 

28 June 2024

The European Medicines Agency’s Committee for Medicinal Products for Human Use (CHMP) has recommended that marketing authorisation should be granted for Pfizer and BioNTech’s recent Omicron JN. 1-adapted monovalent COVID-19 vaccine, COMIRNATY JN 1. The vaccine is intended for use in adults and children aged six months and above.

25 June 2024

Novavax applies for approval from the European Medicines Agency for a type II variation for their updated COVID-19 vaccine for the JN. 1 strain, NVX-CoV2705. The vaccine update will be applicable for people aged 12 years and over. 

6 June 2024

The US FDA’s Centre for Biologics Evaluation and Research held a meeting with the Vaccines and Related Biological Products Advisory Committee (VRBPAC) on 5 June. The result of which was that the FDA are reccomending an update to the COVID-19 vaccine. An updated vaccine that is effective against the latest variant, the JN.1 variant, was determined to be neccessary after a unanamous vote from the committee. The decision from the FDA follows a similar call made by the European Medicines Agency after dialogue with the WHO. 

23 May 2024

Due to a decline in revenue from COVID-19 medications over the past couple of years, Pfizer has implemented cost-cutting measures. The programme aims to reduce costs and save the company around US$1.5 billion by 2027. Revenue from the reduced sales due to lack of demand for it's COVID-19 products, Paxlovid and the vaccine Comirnaty, leading to a decline in revenue for the company by 42% in 2023. 

22 February 2024

Moderna moves away focus from it's coronavirus vaccine, Spikevax, in pursuit of further developments in it's other mRNA ventures. Even with this, the company is still reporting positive use figures for its vaccine, with Spikevax accounting for 48% of the COVID-19 retail market in the USA in the latter part of 2023, compared to 37% in 2022. This brings the therapy close up behind Pfizer’s Comirnaty. Annual sales for Spikevax reached $6.7 billion, with Comirnaty hitting $11.2 for the year. 

“I believe 2024 will be a year where many observers of Moderna go from thinking of us as a COVID vaccine company to seeing Moderna as an mRNA platform company with several products approved and more approvals on the way,” stated Stéphane Bancel, CEO of Moderna.

21 November 2023

In August 2022, Moderna sued competitors BioNTech and Pfizer for patent infringement over the use of mRNA technology in the BioNTech/Pfizer COVID-19 vaccine. Moderna claimed that the big pharma coalition had copied their mRNA technology patented between 2010 and 2016, however BioNTech and Pfizer disputed the claim stating that their vaccine was based on BioNTech's proprietary mRNA technology. Today, the European Patent Office found the claim invalid, ruling in favour of BioNTech and Pfizer. 

Moderna states they will be lodging an appeal against the verdict. 

2 October 2023

The Nobel Prize for Medicine has been awarded to two scientists for their discoveries in mRNA molecules, which laid the groundwork for COVID-19 vaccines. Katalin Kariko, Professor at the University of Szeged in Hungary and adjunct Professor at the University of Pennsylvania, USA, formerly Senior Vice President and Head of RNA protein replacement at BioNTech, and US colleague Drew Weissman. The colleagues developed nucleoside base modifications that prevent the body's immune system from attacking lab-made mRNA. BioNTech went on to develop their mRNA-based COVID-19 vaccine, instrumental in savings millions of lives in the COVID-19 pandemic. 

22 August 2023

In the US, the government is awarding $1.4 billion to be used for the development of new therapies, including vaccines, against COVID-19. The funding incorporates a $326 million contract with the company Regeneron Pharmaceuticals specifically with the aim of developing a next-generation antibody therapy for the prevention of infections. This funding also falls under an initiative from the US Department of Health and Human Services called Project NextGen, to invest $5 billion in the future of healthcare. 

22 August 2023

In another update on the latest vaccine efforts against COVID-19, Novavax has released prelimanary results from their small animal and non-human primate testing phases on the updated XBB protein-based vaccine. The results have demonstrated that the booster initiates an immune response against several forms of the coronavirus, including the newly emerging and spreading Eris variant of the virus. 

18 August 2023

Moderna have released data from their clinical trial testing the latest booster for COVID-19. The trial results so far show that the booster demonstrates a good neutralising antibody response to the newer EG.5 (eris) and FL.1.5.1 (fornax) variants. Eris, a subvariant of Omicron is the most rapidly growing strain in the US at the minute, meaning an effective booster vaccine ready for the next stage of immunisations later in the year will be welcomed. 

01 August 2023

Daiichi Sankyo break new ground in Japan by receiving the first approval from the country for it's COVID-19 mRNA-based vaccine, DS-5670, under the brand name Daichirona. The vaccine was presented to a Japanese Health Ministry panel to be administered as a booster shot after standard immunisation. Throughout the COVID-19 pandemic, Japan has relied upon mRNA-based vaccines from Pfizer and Moderna. This certification puts the vaccine in good stead for full approval in Japan later down the line. 

22 June 2023

Moderna applies for approval for the next stage of updated COVID-19 vaccinations, following the US FDA's reccomendation to focus on developing monovalent vaccines for the next round of boosters to be available on the market. Moderna are confident about their monovalent vaccine containing spike proteins for the XBB.1.5 sublineage, which has already demonstrated a strong immune response against XBB descendent lineage viruses in preliminary trials. 

16 June 2023

Ahead of pharma companies working to update their COVID vaccinations against more recent strains, the US FDA have reccomended they focus on developing monovalent vaccines, instead of bivalent vaccines. The regulation agency are proposing that companies, including Pfizer/BioNTech, Moderna, and Novavax concentrate on the XBB.1.5 subvariant of the virus for the updated vaccinations. 

25 May 2023

The US FDA have now granted full approval to Pfizer for Paxlovid for the treatment of adults at risk of severe disease progression after infection with COVID-19. The oral anti-viral was initial approved for emergency use at the height of the pandemic in 2021. The decision was based on data provided by the FDA and Pfizer, confirming the safety profile of the treatment. 

15 May 2023

In Singapore, the Health Sciences Authority (HSA) has extended the authorisation for Novavax’s COVID-19 vaccine, Nuvaxovid (NVX-CoV2373), for use in individuals aged 12–17 years. The vaccine was originally granted approval for use in adults aged 18 and over in February 2022. Now, Nuvaxovid is among the non-mRNA vaccines included as an option in the national vaccination programme. 

17 April 2023

In a recent multicenter study of inpatients with COVID-19, it was found that the administration of dexamethasone early on was correlated to significantly decreased risk of mortality or discharge to hospice in patients requiring supplemental oxygen. The results indicate that dexamethasone should be continued for use in patients with COVID-19 in hospital. 

23 March 2023

Studies have determined that having a third dose of SARS-CoV-2 vaccines boosts protection against infection with the virus and reduces the risk of hospitalisation. Researchers point out that long-term effects have not been fully established due to the short time period but after 7 months antibody responses were significantly higher in those who had received the third vaccination compared to those who had received 2. 

16 March 2023

From a study undertaken by Kaiser Permanente, the drug Paxlovid (nirmatrelvir-ritonavir) has been shown to prevent hospitalisation in people with mild to moderate COVID-19, when adminstered in the early stages of the disease. The drug is currently avliable for use under the FDA's Emergency Use Authorisation. 

14 March 2023

Pfizer has entered into an agreement with a research group from Emory University – Schinazi Laboratory, led by Raymond Schinazi – to collaborate on looking into antiviral compounds, to determine their potential for use in the treatment of COVID-19. Pfizer will be able to claim exclusive rights to any compounds with promise, and will bear responsibility for carrying them forward into clinical testing phases. 

8 February 2023

After testing the drug peginterferon lambda in the multi-centre Phase III TOGETHER clinical trial, results showed that a single dose of the antiviral reduces the risk of hospitalisation and emergency department visits due to COVID-19 by 50%. The 1,900 participants were mostly vaccinated (84%), but the effects of the drug were found to be consistent between the vaccinated and unvaccinated populations. 

23 January 2023

The US FDA has proposed to shift the management of COVID-19 infections to a similar structure to that for influenza, where the latest COVID-19 vaccine is adminisitered to adults annually. The use of two shots per year is also being considered for children, older adults, and those with a compromised immune system. The regulatory body hopes that by having a simplifieed system, there should be better vaccine developement and greater vaccine coverage. 

20 January 2023

Sinopharm's biotech unit, based in Shanghai, had received approval from the National Medical Products Administration to conduct clinical trials on its mRNA COVID-19 vaccine, specifically to target the Omicron variant of the virus. Sinopharm is the only legal distributor of Merck & Co's antiviral molnupiravir in China. 

16 January 2023

A new rapid test from researchers at Cambridge University uses DNA as 'nanobait' to detect common respiratory viruses such as influenza and COVID-19, all at the same time. The single strands of DNA are programmed to search for specific RNA regions in target viruses, then these 'caught' strands are passed through a nanopore sensor. The sesnor digitalises the information and allows the identification of the structure of the virus. The test can also distinguish between variants. 

3 January 2023

In light of the surge in cases of COVID-19 infection in China, the European Union have offered free vaccines to the country. Representatives from China have not yet stated whether they will be accepting the offer, currently saying they have adequate supplies to meet the demands but would like to strengthen ties with international partners.

22 December

After testing in a randomised controlled trial with over 25,000 participants, it was found that molnupiranir, the antiviral, does not reduce the number of death or hospital admissions in COVID-19 patients who are vaccinated and high risk. However, the drug was found to speed recovery from infection in patients treated at home when compared to the control group. 

19 December

A real-world multi-stage study from Centers for Disease Control and Prevention’s VISION Network has found that the new bivalent mRNA COVID-19 booster vaccines are more effective in providing short-term protection against the virus, than several doses of the original monovalent vaccines. The study showed that patients who had the bivalent booster made 51% fewer visits to urgent care due to COVID-19 than patients who had received monovalent vaccines. 

13 December

As COVID cases continue to increase in China, healthcare providers are using new methods to distribute medicines. The healthcare app allows people who have tested positive for COVID-19 to purchase a box of Paxlovid, which has been authorised for emergency use by the FDA as an oral antiviral medicine. The medicine is being sold for 2,980 yuan ($426.80) per box and sold out within an hour of being listed online. 

13 December

Meiji Seika Pharma have launched a Phase III trial of an mRMA vaccine for COVID-19, to be compared to the mRNA vaccine developed by Pfizer and BioNTech. The trial will take place in Japan and include 780 subjects, with the test period taking place from November to April 2024. 

13 December

Japan-based company Shionogi & Co Ltd have announced today that the Japanese government will be purchasing 1 million doses of Xocova in addition to the million doses previously agreed. Xocova is a protease inhibitor known as ensitrelvir used for treating COVID-19 via oral administration. Xocova received emergency use approval from regulators in Japan last month as cases in the country rise again. 

12 December

The US FDA have granted fast track status for Pfizer and BioNTech's mRNA combined vaccine for COVID-19 and influenza. The Phase I clinical trial of the vaccine was started in November of this year, to test the safety, tolerability and immunogenicity of the vaccine, which encodes for two Omicron strain spike proteins and for the hemagglutinin of four influenza strains. The fast track status will help in the developement and review of the new vaccine. 

6 December

A team of independent, international subject experts, led by Isabelle Boutron of Université Paris Cité and Director of Cochrane France, have undertaken a review into the effectiveness of COVID-19 vaccines from clinical trial data up to November 2021. The review has found that most vaccines reduced the risk of infection with COVID-19 and reduced the risk of severe disease. 

5 December

Pfizer and BioNTech counter sue Moderna over their lawsuit regarding three patents around their COVID-19 vaccines. The pharma giants claim that Morderna have asked for an unreasonable amount in damages and are confident they can defend their intellectual property surrounding the development of the vaccines. 

2 December

The Lee Kong Chian School of Medicine (LKCMedicine) at Nanyang Technological University, Singapore (NTU Singapore) have launched a new laboratory for the sole purpose of researching pandemic viruses. The lab will be fitted with capabilities to allow the safe handling of potetially deadly bacteria and viruses, and hopefully lead to the development of diagnositic tools and vaccines. 

1 December

A year ago a research collaboration from University of North Carolina at Chapel Hill, Weill Cornell Medicine and NewYork-Presbyterian (USA), tested the combination of the Moderna mRNA vaccine and a protein-based vaccine with an adjuvant in infant rhesus macaques, producing a neutralising antibody response. A year on, the group have stated that the vaccine combination still provides a good level of protection against lung infections. 

29 November 

Researchers from a lab at Texas A&M University School of Medicine (TX, USA) have used a synthetic scaffold – DARPin – to engineer proteins that can be used to block the interaction between the SARS-CoV-2 surface protein and the host cell protein. 
“This study offers the possibility of an on-demand nasal spray able to tackle COVID either before or after virus exposure,” concluded Zhilei Chen, lab leader. 

29 November 

A research group from Johns Hopkins Medicine (MD, USA) have published a study in JAMA Network Open suggesting that people who are pregnant and have been infected with SARS-CoV-2 can safely take the antiviral drug Paxlovid and this could mitigate the development of severe disease.

22 November 

This week, Novavax have announced that they are retracting their agreement with Gavi, the Vaccine Alliance, to sell their COVID-19 vaccine to low- and middle-income countries as a part of the COVAX facility. Novavax stated the reasoning behind puling out of the deal as Gavi being unable to complete on the procurement of the 350 million doses it had agreed to buy last year for the facility. 

18 November 

Novavax has gained expanded approval for it's vaccine Nuvaxovid™ for use in Canada after promising data from a Phase II trial. 
"Canadians now have access to our protein-based Nuvaxovid COVID-19 vaccine as an adult booster," stated
Stanley C. Erck, President and Chief Executive Officer, Novavax. "With the winter months upon us, it's important
to have options for vaccination to help protect against COVID-19."

18 November 

Pfizer and BioNTech have announced that their latest Omicron shot shows good results in inital testing stages. Their tailored vaccine has demonstrated a greater immune response to the subvariant BQ.11 than their original vaccine, with a higher number of neutralising antibodies produced in older adults.

10 November 

Sanofi and GSK won approval for their jointly made vaccine booster to be administered to people who have already received a primary shot. The booster, VidPrevtyn Beta, is based lab-made viral proteins, including surface proteins of the beta coronavirus strain, along with an adjuvant developed by GSK. 
"Today’s approval validates our research in developing a novel solution for the COVID-19 pandemic," sommented Thomas Triomphe, head of vaccines at Sanofi.

8 November 

Novavax Inc. have announced that their latest COVID-19 shot, NVX-CoV2515, which has been reworked for use against the Omicron BA.1 variant is effective, as shown by the results from a Phase III trial. The shot triggered a strong immune response when used as the fourth dose, producing 1.6 times more neutralising antibodies in people who had not previously come into contact with COVID-19 than their original vaccine. 
The prototype tailored vaccine gave rise to a broad immune response against the original strain of the virus, and the BA.1 and BA.5 Omicron variants. 

4 November 

A study as part of the KidCOVE clinical trial has found that Moderna's COVID-19 mRNA vaccine is deemed safe and effective for use in children between the ages of 6 months to 5 years. This finding comes after the vaccine was also found to be safe in children of 6 to 11 years of age. 
The results of the two-part study have been published in The New England Journal of Medicine. 
C. Buddy Creech, of Vanderbilt University Medical Center, TN, USA and second author of the paper and team stated:
“Having a safe and effective (COVID-19) vaccine available for infants, toddlers and young children is critically important.”

28 October

Biotechnology company Spiklmm (part of French company Truffle Capital) have developed their first monoclonal antibody against SARS-CoV-2, SPK001. SPK001 has been designed with the aim of providing pre-exposure protection against OCVID-19 to immunocompromised patients. These patients make up 30-40% of those hospitalised for COVID-19 and often show poor responses to the standard vaccination programme. Spiklmm are hoping to test the antibody, along with another, SPK002, in a Phase II trial in immunocompromised patients with the aim of gaining emergency use approval in 2023. 

27 October

Researchers from Yale University (CT, USA) have developed a new nasal vaccine that could help booster immune responses to COVID-19 by kickstarting the immune response in the respiratory system. The team have tested a new 'prime and spike' approach in mice. The mice are vaccinated with a priming intramuscular injection and then followed up with a nasal spray containing spike proteins of coronavirus. The results in mice showed that those who were previously vaccinated and then boosted with the nasal administration showed no disease. 

18 October

Moderna has agreed to supply its new variant-adapted COVID-19 vaccine to a global scheme that aims to deliver vaccinations to the world's poorest countries. Biotech company and vaccine alliance GAVI, which has previously supplied vaccines for the original SARS-CoV-2 strain, will cease their existing supply deal. Moderna will supply up to 100 million doses of the bivalent vaccine at the lowest available price starting from 2023.

14 October

Japan's Fujifilm has halted development on its anti-influenza drug Avigan to treat COVID-19 after over 2 years of effort on the pill. The emergence of the Omicron variant, Fujifilm states, made it difficult to measure the drug's effectiveness in preventing severe symptoms during a Phase III trials, which was cut short. Studies in Japan were inconclusive, causing domestic regulators to delay approval. 

12 October

Hong Kong has approved BioNTech's COVID-19 vaccine for infants and children under 5 years of age. Each shot contains one-tenth of an adult dosage. The government recently approved China's Sinovac vaccines for children 6 months and older, with the BioNTech vaccine and Sinovac as the two vaccines available for Hong Kong residents.

11 October

AstraZeneca and Oxford University researchers have suffered a setback in their attempts to create a nasal-spray mode of administration for their COVID-19 vaccine. Initial testing in human subjects did not yield the desired protection. Only a minority of participants demonstrated an antibody response in the respiratory mucous membranes. The immune response measured in the blood was also weaker than that produced by an injection.

10 October

Swiss drug regulator Swissmedic has temporarily approved Pfizer's COVID-19 booster shot that targets the original and BA.1 Omicron SARS-CoV-2 viral strains. Swissmedic has stated that the data currently available is not yet sufficient to make a permanent decision on the bivalent booster vaccine.

5 October

A Japanese health ministry panel have approved Pfizer's COVID-19 vaccine for children 6 months and older. The panel also recommened the approval of Pfizer's bivalent vaccine that protects against the BA.4 and BA.5 subvariants of Omicron.

4 October

Indonesia's food and drug agency, BPOM, has granted emergency use approval of an mRNA vaccine developed by Chinese biotech company Walvax Biotechnology Co. Ltd. The vaccine has been in development for two years, and targets the original SARS-CoV-2 strain. While large late-stage trials of the vaccine have yet to produce efficacy results to demonstrate the vaccine's risk reduction of COVID cases and deaths, head of BPOM Penny Lukito stated that the vaccine was 83.58% effective against wild-type coronavirus strains considered common and normal. This efficacy dropped to 71.17% against moderate cases of the Omicron variant. 

20 September

HAS, the French Health Authority has cleared two separate COVID-19 boosters targeting the Omicron variant, ahead of an anticipated rise in COVID infections in the coming winter months. The two bivalent shots, developed by Moderna and the Pfizer BioNTech coalition, combat the BA.1 version of Omicron and the original virus first detected in China, and will be administered to high-risk individuals.

14 September

Singapore has granted interim authorisation for Moderna's bivalent COVID-19 booster vaccine, which is designed to target the original 2020 SARS-CoV-2 variant and the Omicron variant that circulated in winter 2021.

Moderna has announced they are in talks with the Chinese government about supplying COVID-19 vaccines to the country. As China continues to lock down sections of their society while other nations open up, this move is a step towards the approval of foreign COVID vaccines, something that has yet to be done in the country.

9 September

The COVAX facility, aimed at immunization efforts in poorer countries and backed by the WHO and the Global Alliance for Vaccines and Immunization (GAVI), have reported the delivery of 1.72 billion COVID-19 vaccine doses to 146 countries. 

6 September

A recombinant nasal vaccine developed by Bharat Biotech has been approved by the Indian drug regulator, with approval granted for primary immunisation in those 18 years and older, as well as restricted emergency use.

29 August

Swiss drugs regulator Swissmedic have approved the first bivalent COVID-19 booster vaccine in Switzerland. The Spikevax vaccine developed by Moderna is the same vaccine approved by the UK earlier in the month for anyone 18 years or older.

Japan's health ministry stated that its panel of experts have agreed to approve the manufacturing and sale of AstraZeneca's COVID-19 preventive treatment Evusheld. The treatment is designed to protect against infection for at least 6 months, and has been deployed in nations for individuals with compromised immune systems who see little to no benefit from vaccines. The panel also consented to using Pfizer's COVID-19 vaccine as booster shots for children aged 5-11.

23 August

Pfizer and its vaccine partner BioNTech have filed for US authorisation of its COVID-19 booster vaccine, which has been adjusted to target the Omicron variant. The US Food and Drug Administration (FDA) will make the decision to approve the bivalent shot containing the dominant BA.4 and BA.5 variants of the virus, as well as the original strain. Pfizer said it would have doses available to ship immediately after regulatory clearance. 

22 August

The US Food and Drug Administration (FDA) has asked Pfizer to test the effects of an additional course of its oral antiviral Paxlovid among people who experience a rebound in COVID-19 treatment. The health regulator told Pfizer that it must produce the initial results of a randomised controlled trial of a second course of the drug by September 30. 

17 August

Novavax has filed for US authorisation for use of its COVID-19 vaccine as a booster dose in people who had either received its shots or a different vaccine. The company's protein-based vaccine was authorised in the US in July, and many hoped its traditional technology would convince vaccine sceptics to get inoculated. 

A new study has found blood abnormalities in people with Long Covid, a condition that causes extended symptoms after SARS-CoV-2 infection. The exploratory study examined 99 people with Long Covid, looking at 'granular aspects of the T cells and antibody response'. It found that most Long Covid patients had low levels of cortisol, a stress hormone that helps the body control inflammation, glucose, sleep cycles, and more. Read full details here. 

16 August

The United Kingdom has become the first country to approve Moderna's variant-adapted vaccine that targets both the original version and the Omicron variant of the virus. The UK medicines regulator (MHRA) gave the bivalent vaccine conditional approval as a booster for adults on Monday. The UK's Joint Committee on Vaccination and Immunisation also backed use of the variant-adapted shot in the country's booster campaign, set to begin in September. 

10 August

The European Medicines Agency (EMA) has started a rolling review of the variant-adapted COVID-19 vaccine from Pfizer and BioNTech. The bivalent vaccine targets two strains of the SARS-COV-2 virus - the original strain first identified in China and the Omicron subvariants BA.4 and BA.5, which are known for being highly transmissable. A rolling review means that the EMA assesses the data as it becomes available and the process continues until there is enough data to make a formal marketing application. 

3 August

A small trial testing the efficacy of a drug made by Axcella Health aimed at easing long COVID symptoms helped some patients to recover from lingering physical and metal fatigue, but failed to restore the function of patients' mitochondria - the study's main goal. In the 41-person pilot study, three of 21 patients who received the drug returned to normal levels of physical fatigue after 28 days of treatment. Others who received the drug also reported physical and mental improvements that were deemed statistically significant. 

The Omicron variant may be more efficient at infecting children through the nose than previous versions of the virus, according to the results of a small study. The study found that antiviral defenses in children's noses are 'markedly less pronounced in the case of Omicron.' It also found that Omicron reproduced itself more efficiently in children's nasal lining cells compared to Delta and the original virus. 

2 August

Scientists around the world have warned of fresh waves of COVID-19 cases as winter looms in the northern hemisphere. In the United States, the head of the Institute of Health Metrics and Evaluation said cases could double compared to the current daily tally. In the United Kingdom and Europe, scientists predict a series of COVID waves as people spend more time indoors, with very few mask or social distancing restrictions in place. With that said, deaths and hospitalisations are not expected to rise to the same degree due to widespread vaccination and increased immunity from previous infections. 

The World Health Organisation has designated a Swiss laboratory as the next in a global network of high-security labs that will grow, store and share newly discovered microbes that could unleash the next pandemic. The WHO's BioHub programme was initiated - in part - due to the issues faced by researchers in getting samples of the SARS-Cov-2 virus when the pandemic broke out in early 2020. 

27 July

Researchers have said that an experimental chewing gum that reduces Omicron particles in saliva hold promise for curbing transmission of the virus. The gum contains copies of the ACE2 protein found on cell surfaces, which the coronavirus uses to break into cells to infect them. In test tube experiments that used saliva from infected patients, the virus particles attached themselves to the ACE2 receptors in the chewing gum and the viral load fell to undetectable levels. Researchers are preparing to launch the first human trial, which will require COVID-19 patients to chew four ACE2 gum tablets each day for four days. 

Omicron's BA.5 subvariant is estimated to make up almost 82% of COVID cases in the United States for the week ended July 23, according to the US Centers for Disease Control and Prevention. This represents a jump from the previous week, when BA.5 made up 75.9% of cases in the country. The BA.5 subvariant has been driving a surge in new infections globally and has been shown to be particularly good at evading immune protection. 

BioNTech and Pfizer filed a complaint with the US District Court of Massachusetts this week, seeking a judgement that they did not infringe US patents held by CureVac. The lawsuit accused CureVac of trying to profit from the success of BioNTech and Pfizer's COVID-19 vaccine after CureVac's efforts to create its own vaccine failed. CureVac alleges that BioNTech and Pfizer infringed its intellectual property rights related to the use of mRNA technology. 

20 July

A World Health Organisation (WHO) official has called on European countries to re-up vaccination efforts and reinstate some COVID measures to curb the surge in cases on the continent. WHO Regional Director Hans Kluge said countries should bring back mask wearing and accelerate vaccine uptake to avoid overwhelming health systems later in the year, as the BA.4 and BA.5 Omicron subvariants continue to spread rapidly. Almost 3 million new cases were recorded in Europe this week, which accounted for almost half of all global cases. Officials are concerned that rising cases will put even more strain on public health systems during the autumn and winter, as the weather cools and social activities move indoors.

The US Centers for Disease Control and Prevention (CDC) announced this week that the Omicron BA.5 subvariant now makes up 78% of cases in the United States for the week ended July 16. BA.5, which is particularly good at evading immune protection, has been driving the recent surge in global COVID cases. Vaccine manufacturers have been asked by health regulators to target the BA.4 and BA.4 variants with the shots to be rolled out this autumn. 

The European Union has signed a joint procurement deal with Gilead Sciences for its COVID antiviral Veklury. Twenty-two EU member states are participating in the deal, under which they can purchase up to 2,250,000 vials. This is the second  contract for the drug to be approved in Europe. Veklury is used to treat COVID patients at high risk of experiencing severe symptoms, as well as patients who have pneumonia and require supplemental oxygen. 

14 July

This week featured a raft of vaccine approvals in several major markets - 

In the US, the Food and Drug Administration (FDA) approved Novavax Inc's COVID-19 vaccine, making it the fourth COVID shot to be authorised for use in adults in the country. The Novavax vaccine is protein-based and offers an alternative to mRNA vaccines (produced by Pfizer and Moderna) and vector vaccines (produced by AstraZeneca and Janssen). Health authorities have previously expressed hope that the vaccine's utilisation of traditional technology will elicit wider acceptance among vaccine sceptics. Sign-off is still required from the US Centers for Disease Control and Prevention (CDC) before the shots can be made available to the public. 

Moving south, Brazil's Health Regulatory Agency gave its stamp of approval to Sinovac's COVID-19 vaccine (CoronaVac) for emergency use in children between 3 and 5 years old. These children will receive the same dose as people in the 6-17 age group and there is no restriction on the application for immunosuppressed children. 

13 July

AstraZeneca announced this week that a review of real world data (RWD) shows the company's COVID-19 vaccine provided equally effective protection against hospitalisation and death after two doses compared to mRNA vaccines. 

The US Centers for Disease Control and Prevention has said that the BA.5 strain of Omicron is estimated to make up 65% of all coronavirus cases in the United States, as of last week. The BA.5 and BA.4 sub-variants together accounted for more than 80% of circulating variants last week. These fast-spreading strains are more transmissible than their predecessors and are fuelling the global rise in case numbers. 

The World Health Organization has ruled that COVID-19 remains a health emergency, after a meeting of its Emergency Committee. The committee, which is made up of independent experts, said the ongoing evolution of the virus and pressure on health services means the disease still warrants the emergency designation, almost two and a half years after it was first identified. 

8 July

Africa's Centers for Disease Control and Prevention (CDC) has signed a memorandum of understanding with Pfizer for the continent to receive supplies of its COVID-19 oral antiviral Paxlovid. The MOU will make Paxlovid available to African countries at cost. Paxlovid has proved extremely effective against COVID-19, with a study last November demonstrating 90% efficacy in preventing hospitalisations and deaths from the virus. 

A new study technique is facilitating the detection of new COVID variants earlier. With just a small amount of raw sewage and a new analysis technique, researchers at the University of California, San Diego campus have been able to determine the genetic mixture of SARS-COV-2 variants in the community and detect new variants up to 14 days before they can be detected in nasal swabs. 

The European Medicines Agency has said it is open to using COVID-19 vaccines that target older subvariants of the Omicron variant this autumn, as cases continue to rise due to new subvariants. Vaccines designed to target the newer BA.4 and BA.5 strains have only recently entered clinical development. According to Marco Cavaleri, the EMA's head of health threats and vaccines strategy: 'That's why for the time being we still think that it's very good to keep all options open and to not exclude any of these candidates from any potential approval.'

6 July

The European Commission has approved the expanded conditional marketing authorisation of Novavax's Nuvaxovid COVID-19 vaccine for children aged 12-17 in the European Union. The approval follows a positive recommendation from the European Medicines Agency's Committee for Medicinal Products for Human Use last month. 

29 June

Advisers to the US Food and Drug Administration have recommended a change to the design of COVID-19 booster vaccines this autumn in order to protect against the most recently circulating variants. The FDA's Vaccines and Related Biological Products Advisory Committee voted 19-2 that the next round of COVID booster shots should be effective against the Omicron variant. The FDA plans to decide on the design of the boosters by early July.

28 June

The US Food and Drug Administration's advisory committee is set to meet today to discuss preparations for the likely wave of Omicron infections this winter. They will discuss whether to deploy vaccines that specifically target the Omicron variant, which includes Moderna's bivalent vaccine and candidates from the Pfizer/BioNTech collaboration. 

Chinese biotech Clover Biopharmaceuticals has said that a booster shot of its COVID-19 vaccine candidate significantly increased antibody response against the Omicron variant from levels seen after two primary doses. A third dose of the SCB-2019 vaccine candidate caused a 19-fold increase in neutralising antibody levels against the Omicron BA.2 subvariant from pre-booster levels. 

24 June

An experimental COVID vaccine from Sanofi and GSK has been found to be effective against the Omicron variant, according to late-stage data. The bivalent vaccine targets the Beta variant, which was first identified in South Africa in late 2020, as well as the original strain of the virus. In a trial involving 13,000 adults, the vaccine demonstrated an efficacy rate of 64.7% against symptomatic COVID and 72% against the Omicron variant. 

The European Medicines Agency (EMA) endorsed Valneva's COVID-19 vaccine this week, though it remains unclear whether the company's supply agreement with the European Commission will continue. The French vaccine maker has been trying to salvage the deal after the company's marketing application was delayed due to the EMA requesting more information. The original deal was for up to 60 million doses, but the European Commission has since indicated that it would like to reduce the order. 

22 June

Moderna's Chief Executive Stephane Bancel has said the company's variant-targeting COVID-19 vaccine will be ready to ship in August as the company has been manufacturing doses ahead of regulatory approval. He said that all the data would be filed by the end of June and expressed hope that the vaccine would be approved by August. Similarly, Pfizer CEO Albert Bourla confirmed that vaccines targeting Omicron and other variants are in development, adding that the company would be able to quickly adapt their shots as the virus mutates. 

Moderna also announced plans for a new COVID-19 vaccine facility this week. The company will build a new research and manufacturing centre in the UK which will be used to develop vaccines against new COVID-19 variants and other respiratory illnesses. 

17 June

A new, peer-reviewed study has found that the Omicron variant of the coronavirus is less likely to cause long COVID than previous variants. The study, conducted by researchers at King's College London, found the odds of developing long COVID after Omicron infection were 20% to 50% lower compared to the Delta variant. This figure varied depending on the person's age and when their last vaccination was. 

15 June

Several European Union countries have called on Pfizer and other vaccine makers to renegotiate their contracts, saying that millions of doses that are no longer needed could go to waste. Countries are hoping to reduce their vaccine supplies after placing huge orders in the midst of the pandemic. The issue was discussed on Tuesday at a meeting of EU health ministers in Luxembourg.

Advisers to the US Food and Drug Administration have unanimously recommended that the agency authorises the Moderna COVID-19 vaccine for children aged between 6 and 17. A committee of outside experts also met on Wednesday to discuss the authorisation. 

14 June

Sanofi says an upgraded version of the COVID-19 vaccine candidate it is developing with GSK showed potential to provide protection against the virus's main variants of concern, including the Omicron BA.1 and BA.2 strains, when used as a booster dose. The GSK-Sanofi vaccine candidate is currently undergoing review by the European Medicines Agency. The French drugmaker added that the vaccine was shown to significantly boost antibody levels against a number of variants of concern during two trials. 

Valneva lost around a quarter of its market value on Monday (June 13) after the company disclosed the future of its COVID-19 vaccine is in jeopardy. Valneva has been trying to salvage a deal with the European Commission, which indicated it would terminate an advance purchase agreement for up to 60 million doses. Oversupply is thought to be the reason for the potential deal termination. 

The World Bank has approved a loan of €454.4 million to help South Africa fund COVID-19 vaccine purchases. The funding will retroactively finance the procurement of 47 million doses by the South African government. 

13 June

US Food and Drug Adminstration (FDA) reviewers have said the Moderna COVID-19 vaccine appears safe and effective for use in children aged six months to 17 years. The panel noted that the vaccine has a similar side effect profile in children as it does in adults, as well as generating a similar immune response. A committee of scientists will meet later this week to vote on whether to recommend that the FDA authorise the vaccine for use in children. 

The antiparisitic drug ivermectin does not meaningfully reduce the time needed to recover from COVID-19, according to a large study published yesterday. It is the largest of several clinical trials to show the drug, which was touted as a treatment since the beginning of the pandemic, is not effective against the virus.

7June

The FDA advisory committee has recommended that the agency approve Novovax's COVID-19 vaccine, a late entrant to the vaccine field, for use in adults. If Emergency Use Authorization is granted by the FDA, the Novavax COVID-19 vaccine would become the first protein-based COVID-19 vaccine available in the U.S.

Stanley C. Erck, President and Chief Executive Officer, Novavax said: "The advisory committee's positive recommendation acknowledges the strength of our data and the importance of a protein-based COVID-19 vaccine developed using an innovative approach to traditional vaccine technology. In today's VRBPAC meeting, we heard the overwhelming support for our vaccine from physicians, healthcare organizations, and consumers who are eagerly anticipating a protein-based vaccine option."

6 June

Pfizer announces plans to invest $120 Million to produce PAXLOVID, their COVID-19 oral treatment, at the Kalamazoo, Michigan site. The move further strengthens the drug maker's commitment to US domestic manufacturing.

Mike McDermott, Chief Global Supply Officer at Pfizer commented: “Pfizer’s Kalamazoo facility has been at the forefront of pharmaceutical manufacturing for more than 135 years through the legacy company Upjohn. The Kalamazoo facility uses some of our most innovative manufacturing technology and has been essential in Pfizer’s fight against COVID-19, producing nearly one billion doses of COVID-19 vaccine at the site to date. Through this expansion, we will continue to invest in the next generation of manufacturing and supply chain resilience.”

31 May

The results of a recent blood survey show that South Africa experienced a fifth wave of COVID-19 infections despite 97% of the population having antibodies due to previous infections or vaccination. The study examined 3,395 samples from blood donors earlier this year, which showed that 87% of South Africans had previously been infected with the virus, while just over 97% had either previous infection, vaccination, or both. The findings demonstrate the ability of the Omicron variant, particularly its BA.4 and BA.5 sublineages, to infect those who already have protection from the disease. 

Some US doctors are changing tack when it comes to recommending use of Pfizer's oral COVID-19 antiviral Paxlovid for lower risk patients, despite usage spiking last week. This comes after an advisory from the US Centers for Disease Control and Prevention (CDC) saying that patients can experience a recurrence of COVID-19 symptoms after completing a course of Paxlovid treatment and recommending that they isolate again for five days if this happens. Speaking to Reuters, infectious disease specialist Dr. Sandra Kemmerly noted that the possibility of an extended quarantine period is 'not a crowd pleaser' and said: 'For those people who are really not at risk.. I would recommend they not take it.' 

25 May

The US Centers for Disease Control and Prevention (CDC) has published a report about post-COVID conditions in adult survivors of the disease. The report finds that COVID survivors have twice the risk for developing pulmonary embolism or respiratory conditions, while one in five survivors between the ages of 18 and 64 experienced at least one condition that may be attributable to previous COVID. 

Nigeria has received 4.4 million doses of the Johnson & Johnson COVID-19 vaccine from Spain, in addition to 2 million doses from Finland, Greece and Slovenia. Faisal Shuaib, head of the National Primary Health Care Development Agency (NPHCDA), said the goal was to vaccinate 70% of its population, but Nigeria is currently far off its target. 

Multiple NGOs and civil society groups have called for US President Biden to press for changes in a draft agreement on waiving intellectual property rights for COVID-19 vaccines. In a letter sent to Biden on Monday, the group said an 'outcome document' reached after months of discussions between the main parties - the US, European Union, India, and South Africa - fell short of its goal of removing IP barriers for COVID vaccines. The issue is expected to be discussed during an informal meeting at the World Economic Forum in Davos, Switzerland this week. 

24 May

The US Centers for Disease Control and Prevention (CDC) issued an advisory today saying that patients who experience a recurrence of COVID-19 symptoms after completing treatment with Pfizer's oral antiviral Paxlovid should isolate again for five days. Pfizer has said rebounding symptoms are rare, but some social media users have reported symptoms coming back in recent days. 

18 May

The US National Institutes of Health is in talks with Pfizer about studying whether a longer course of the company's COVID-19 antiviral treatment Paxlovid is needed to prevent reinfections. NIAID Director Anthony Fauci said: 'We're going to be planning what studies we're going to be doing relatively soon, within the next few days' in order to determine whether a longer course is needed. More than 660,000 courses of Paxlovid pills have been administered in the US so far. 

The world is no better prepared to deal with a new pandemic than it was pre-COVID, and may actually be in a worse position due to the financial toll, according to a World Health Organization panel set up to evaluate the global response. The Independent Panel for Pandemic Preparedness and Response said this is due to a lack of progress on reforms such as international health regulations. While the report acknowledged some progress, it concludes that changes are moving much too slowly. 

13 May

Swiss drug regulator Swissmedic has authorised the use of Moderna's COVID-19 vaccine for children between the ages of six and eleven. Moderna said the approval was for two 50 microgram doses. 

South Korea says it will provide COVID-19 vaccines and other medical supplies to North Korea, after the North reported its first outbreak of the virus. At least one person confirmed to have COVID-19 has died in North Korea and the disease is said to be spreading 'explosively'. Before this week, the country had reported no cases since the beginning of the pandemic. 

11 May

The US Food and Drug Administration has approved a new indication for Olumiant (baricitinib) for the treatment of COVID-19 in hospitalised adults requiring supplemental oxygen, mechanical ventilation or extracorporeal membrane oxygenation. Olumiant is the first immunomodulatory treatment for COVID-19 to receive FDA approval. 

The head of the World Health Organization has criticised China's zero-Covid policy, saying it is unsustainable. WHO Director-General Tedros Adhanom Ghebreyesus said a shift in Chinese policy 'would be important' given what is now known of the virus and what is expected in the future. 

BioNTech completed a Phase II clinical trial of its COVID-19 vaccine in China in January, but has yet to release its results. The mRNA vaccine, developed with Pfizer, is one of the most widely used COVID-19 vaccines worldwide but has not yet received approval in China, which has vaccinated the majority of its population with domestically-produced non-mRNA vaccines. 

Novavax shares fell almost 20% in premarket trading on Tuesday due to uncertainty over global demand for the company's COVID-19 vaccine. The company said in September that it was aiming to deliver 2 billion doses in 2022. It confirmed this week that it delivered about 42 million doses in the first quarter of the year and added it has not yet received an order from Gavi, the global vaccine alliance.

9 May

A new study shows severe obesity may weaken the effectiveness of COVID-19 vaccines in those who have never been infected with the coronavirus. Among those in the study who had not been previously infected and received the Pfizer-BioNTech vaccine, patients with severe obesity had antibody levels more than three times lower than normal-weight individuals. Among those who received Sinovac Biotech's CoronaVac, those with severe obesity and no prior infection had antibody levels 27 times lower than normal weight people, according to data being presented this week at the European Congress on Obesity in the Netherlands. 

BioNTech announced today that its first-quarter sales and earnings more than tripled thanks to demand for its COVID-19 vaccine, developed with Pfizer. However, the German company reaffirmed its forecast for a full-year decline in vaccine sales, predicting revenues between €13 billion and €17 billion for 2022, down from €19 billion last year. The company says a high volume of orders placed in late 2021 and the emergence of the Omicron variant contributed to the surge in Q1 sales. 

5 May

The US Food and Drug Administration has restricted the use of Johnson & Johnson's COVID-19 vaccine due to the threat of rare but serious blood clots. In a statement on Thursday, the agency said its use was limited to those 18 and older who cannot access other vaccines. Also excluded from the restrictions are those who 'elect to receive the Janssen COVID-19 Vaccine because they would otherwise not receive a COVID-19 vaccine'. 

4 May

A new study has found that people who experience severe COVID-19 infections suffer the same level of cognitive impairment as people between the ages of 50 and 70. This is the equivalent of losing 10 IQ points, according to researchers from the University of Cambridge and Imperial College London. It found that cognitive recovery is gradual at best and many people continue to report cognitive symptoms six months after infection. The symptoms they report include fatigue, brain fog, problems recalling words, sleep disturbances, anxiety and even post-traumatic stress disorder. 

The Omicron subvariant BA.2.12.1 has been attributed as the cause of rising COVID-19 cases in the US. So far it is spreading 25% faster than its parent virus, BA.2, and accounts for nearly 37% of all cases across the US, according to estimates from the Centers for Disease Control and Prevention. 

2 May

Moderna says its COVID-19 vaccine for children under six years old will be ready for review by the US Food and Drug Administration (FDA) when it meets in June. The company sought emergency use authorisation from the FDA last Thursday. Moderna's chief medical officer, Dr Paul Burton, said the company is "very confident" going into the application review. 

Pfizer says its COVID-19 oral antiviral treatment Paxlovid is not effective at preventing coronavirus infection in members of the same household, according to results from a large trial. The trial enrolled 3,000 adults who were household contacts exposed to an individual experiencing symptoms and having recently tested positive for COVID-19. Those who took a five-day course of Paxlovid were 32% less likely to become infected than those taking the placebo, however the results were not statistically significant and could have been due to chance. 

AstraZeneca has said its vaccine still has market potential, despite expected global oversupply of doses and delay in US approval. CEO Pascal Soriot said on Friday: 'We believe this vaccine still has potential, it's very easy to administer and distribute. The volume in the future will be less because people probably will only need one booster per year and not everyone will take it.'

A US Food and Drug Administration committee is set to review Novavax' COVID-19 vaccine in early June. The FDA's Vaccines and Related Biological Products Advisory Committee will review the NVX-CoV2373 vaccine for active immunisation against SARS-CoV-2, making it the first protein-based COVID vaccine to be reviewed by the committee. 

26 April

The US Food and Drug Administration (FDA) has granted the first full approval for treatment of COVID-19 in children 28 days and older to Gilead Science's drug remdesivir. The announcement comes months after the drug's emergency use authorisation was expanded to include children below 12 years of age and weighing at least 3.5 kg. It is the first approved COVID-19 treatment for children younger than 12. 

French vaccines company Valneva has secured new financing with US-based healthcare investment firms Deerfield Management Company and OrbiMed. Valneva said it had agreed to increase the principal amount of its existing $60 million debt financing agreement with up to an additional $40 million with the Deerfield and OrbiMed. The extension would provide Valneva with immediate access to $20 million, with an additional $20 million available upon conditional approval of its COVID-19 vaccine candidate by the European Medicines Agency (EMA). Valneva's inactivated vaccine candidate VLA2001 has been conditionally approved in the UK, but the EMA has requested more information from the company. 

25 April

An experimental treatment from Shionogi & Co has shown rapid clearance of the virus that causes COVID-19, according to new data from a Phase II/III clinical trial. The pill, S-217622, demonstrated "rapid clearance of the infectious SARS-CoV-2 virus" and is now being evaluated by Japanese regulators. Shionogi is said to have global aspirations for the antiviral once approved. 

Vaccines company Valneva says the European Medicines Agency has asked it to provide more information over its COVID-19 vaccine candidate, despite Valneva's expectation that the vaccine would be approved by the end of this month. The VLA2001 vaccine is easier to store than market rivals as it does not require ultra-cold storage and was approved in the UK earlier this month. 

22 April

The World Health Organization (WHO) endorses the use of Pfizer's COVID-19 oral treatment Paxlovid in high-risk patients after an analysis of trial data showed the therapy dramatically cut the rate of hospitalisation. It says Paxlovid is by far the most potent of all available treatments. 

CureVac and GlaxoSmithKline's second-generation vaccine candidate targeting two recent COVID variants has been shown to be highly effective in preclinical studies on mice, according to CureVac. The study showed the bivalent vaccine candidate, designed to work against Beta and Delta variants, elicited neutralising antibody levels comparable to monovalent vaccine candidates targeting only one of the variants. 

20 April

Moderna says a COVID-19 booster designed to target the Beta variant as well as the original coronavirus generated a better immune response against a number of virus variants, including Omicron. The company says the results are a good sign for future shots targeting two variants. 

Poland has declined to take or pay for any more COVID-19 doses under the European Union's supply contract, a move which will likely cause a legal battle with manufacturers. The country has seen lower vaccine uptake than most of the EU and has surplus vaccine stock, which it has sold or donated to other countries. However, Poland cannot directly terminate the contract for the supply of vaccines as they were signed by the European Union and manufacturers. Polish Health Minister Adam Niedzielski said the consequence would be a 'legal conflict, which is already taking place'. 

19 April:

Researchers are considering trialling Pfizer's oral antiviral Paxlovid for the treatment of long COVID after reports of two patients experiencing relief from their symptoms by using the drug. Long COVID affects approximately 30% of people previously infected with the coronavirus and is synonymous with symptoms such as pain, fatigue, brain fog, breathing issues and exhaustion after light physical activity.

Japan has approved Novavax Inc's COVID-19 vaccine, which is to be manufactured domestically by Takeda Pharmaceutical Co. The Japanese government has agreed to purchase 150 million doses of the recombinant protein type vaccine. Most COVID vaccines administered in Japan to date have been the mRNA type manufactured by Pfizer and Moderna. 

14 April:

The US has renewed the COVID-19 public health emergency, allowing millions to keep access to free tests, vaccines and treatments for at least three more months. The public health emergency has been renewed each quarter since January 2020 and was due to expire on April 16. The US Department of Health and Human Services said it would give 60 days' notice before termination or expiration. 

The UK will expand access to Pfizer's COVID-19 treatment Paxlovid by adding it to a trial to assess how best to use it in a highly vaccinated population. Paxlovid will be added to a Panoramic national study in England, which is making antivirals available to a wide number of patients while collecting data on how best these drugs should be used in a vaccinated adult population. 

13 April:

Pfizer CEO Albert Bourla said today that the company could potentially develop a new vaccine that protects against the Omicron variant as well as older variants of COVID-19 by autumn.  

The BA.2 Omicron subvariant of the coronavirus is responsible for 86% of US COVID-19 cases, according to new data from the US Centers for Disease Control and Prevention (CDC). It is responsible for more than 90% of infections in the US Northeast. 

The new COVID-19 subvariant Omicron XE, first found in the UK, has now been detected in Japan. Omicron XE is a recombinant variant, meaning it is a mix of two earlier Omicron strains, BA.1 and BA.2. Just over 1,000 cases have been detected in the UK so far. 

A study published by The Lancet shows all currently circulating Omicron subvariants evade neutralisation by vaccine-induced antibodies with "comparably high efficacy", suggesting that increased antibody evasion is not the reason for the sharp rise in BA.2 in several countries. Fully vaccinated people (three doses) saw the most potent antibody response. 

12 April:

The World Health Organization (WHO) says it is tracking a few dozen cases of two new sub-variants of the Omicron strain to assess whether they are more infectious or dangerous. It has added BA.4 and BA.5, sister variants of the original BA.1 Omicron variant, to its list for global monitoring. 

11 April:

Taiwan has placed an order for 700,000 units of Pfizer's COVID-19 oral antiviral pill Paxlovid as infections in the country continue to rise. Taiwan's Health Ministry said the order would cover 3% of the population, with half of the units due to arrive in the second quarter of this year. 

Japan has cancelled the purchase of around 40 million AstraZeneca COVID-19 vaccine doses it agreed to buy last year. Japan had originally agreed to buy 120 million doses, with the majority made domestically by Daiichi Sankyo Co. and other local partners. Of the doses delivered so far, about 200,000 have been supplied to local governments and 63 million donated overseas. The country has predominantly relied on mRNA vaccines produced by Pfizer and Moderna for inoculations and boosters. 

8 April:

Moderna has recalled 764,900 doses of its COVID-19 vaccine made by contract manufacturer Rovi after a vial was found to have been contaminated by a foreign body. The company says no safety issues have been identified yet and the full batch is being recalled out of an 'abundance of caution'. The impacted batch was dispersed between Norway, Poland, Portugal, Spain and Sweden in January. 

EU health agencies have said it is too early to recommend a fourth COVID-19 vaccine dose for the general population. The European Centre for Disease Prevention and Control and the EMA's COVID-19 taskforce agree that a fourth dose can be given to people aged 80 and above, but said in a joint statement that there is no clear evidence to indicate that vaccine protection against severe disease is waning substantially in adults aged 60-79. They said they will continue to monitor the situation and cautioned that a fourth dose may become necessary if the epidemiological situation changes. 

6 April:

The US FDA announced yesterday that GlaxoSmithKline and Vir Biotechnology's antibody therapy sotrovimab is no longer authorised as a COVID-19 treatment, with data suggesting it is unlikely to be effective against the Omicron sub-variant BA.2. The agency had already pulled authorisation for the therapy in much of the US northeast last month. 

COVAX, the global project to share COVID-19 vaccines, and the African Union have declined the offer to purchase additional doses of Moderna's vaccine due to issues allocating supplies. Moderna confirmed the global alliance did not exercise the option to buy 166 million doses for the third quarter of 2022, as well as 166 million for the fourth quarter. As supply increases, many developing countries have faced issues such as gaps in cold chain storage, vaccine hesitancy and lack of funds to support distribution networks. 

A new report says it will take $15 billion in grants this year and an additional $10 billion annually after that to establish and maintain an adequate toolkit to respond to COVID-19 and address future pandemic threats. The estimate was included in a paper published by the International Monetary Fund in collaboration with the Coalition for Epidemic Preparedness Innovations (CEPI), the Global Fund and Wellcome Trust. 

4 April:

The World Health Organization has suspended UN supply of the Covaxin COVID-19 vaccine, produced by Bharat Biotech, to allow the manufacturer to upgrade facilities and address deficiencies found in an inspection. The WHO said the vaccine is effective and no safety concerns exist, but the suspension is due to outcomes of a post emergency use listing inspection that was conducted in mid-March. 

China's National Medical Products Administration has approved CanSino Biologics' clinical trial application for its mRNA COVID-19 vaccine. Pre-clinical trial results show CanSino's vaccine can induce high-titer neutralising antibody levels against multiple coronavirus variants, including the Omicron variant.

The US Food and Drug Administration has granted Priority Review for Genentech's Actemra (tocilizumab) intravenous for the treatment of COVID-19 in hospitalised adults who are receiving frequent corticosteroids and require supplemental oxygen. A decision on US FDA approval is expected in the second half of the year. 

30 March:

The US FDA has authorised a second booster dose of the two most commonly used COVID-19 vaccines for people aged 50 and older. The boosters, either Pfizer-BioNTech or Moderna, are to be administered at least four months after the previous dose. The FDA also authorised a second booster dose for younger people with compromised immune systems - Pfizer-BioNTech for those 12 and older and Moderna for those 18 and older. The US Centers for Disease Control and Prevention backed the recommendation. 

The European Medicines Agency (EMA) has launched a review of a COVID-19 booster vaccine made by Spanish pharmaceutical firm HIPRA, saying early results showed it was effective against the Omicron variant. The HIPRA vaccine, going by the brand name PHH-1V, is protein-based and designed for adults who have already received a different COVID-19 vaccine. It needs EMA approval before it can be authorised in the EU. 

28 March:

A new Israeli study shows getting a second COVID-19 booster significantly reduces the risk of dying from the virus. Senior citizens who received a second booster of Pfizer-BioNTech's COVID-19 vaccine had a 78% lower mortality rate than those who only received one. The 40-day study included more than half a million people aged between 60 and 100. It has not yet been peer-reviewed. 

25 March:

The European Medicines Agency has recommended the use of AstraZeneca's antibody medication Evusheld by some vulnerable people to avoid getting sick with COVID-19. They advise its use in people age 12 and over before potential exposure to COVID-19, to prevent future infections. It is now up to the European Commission to officially authorise the drug. Evusheld received US FDA approval in December, while the UK authorised it last week. 

Thailand has placed an order for 50,000 treatment courses of Pfizer's oral COVID-19 drug Paxlovid. The drug will be allocated to patients in high-risk groups. Thailand's Food and Drug Administration granted approval to Paxlovid in January.

23 March:

South Korea grants emergency approval for the use of Merck's COVID-19 pill for adults. The molnupiravir pill, branded as Lagevrio, is the second oral antiviral to be authorised in South Korea after Pfizer's Paxlovid. Lagevrio is only authorised for use by people 18 and older who cannot use injection medications or Paxlovid. 

Moderna announces plans to develop two new mRNA vaccines, building on the company's COVID-19 vaccine efforts. The development programs include a combination respiratory vaccine candidate (dubbed mRNA-1230) and a new program against all four of the endemic human coronaviruses (mRNA-1287). Moderna says mRNA-1230 is designed to be used as an annual booster and targets the three most significant viruses that cause respiratory diseases in adults: SARS-CoV-2, influenza and respiratory syncytial virus. The mRNA-1287 will not include the SARS-CoV-2 virus, but instead comprises HCoV-229E, HCoV-NL63, HCoV-OC43 and HCoV-HKU1, which cause 10%-30% of upper respiratory tract infections in adults. 

Pfizer's vaccine partner claims rival companies are considering patent lawsuits over the Comirnaty vaccine. Acuitas Therapeutics, Pfizer's partner on vaccine delivery tech, has sued Arbutus and Genevant Sciences, claiming they are eyeing "hundreds of millions, if not billions, of dollars in unjustified royalties" through a potential lawsuit. Acuitas says it was after the commercial success of Comirnaty that Arbutus and Genevant made the "spurious claim" that the vaccine may infringe Arbutus' patents. Arbutus and Genevant have not yet taken legal action against Pfizer for alleged infringement. 

22 March:

The US Food and Drug Administration announced plans to hold a meeting of its Vaccines and Related Biological Products Advisory Committee (VRBPAC) on April 6 to discuss considerations for future COVID-19 vaccine booster doses. Representatives from the US Centers for Disease Control and Prevention and National Institutes of Health will also participate in the meeting. The group is expected to discuss what might warrant changing the composition of COVID-19 vaccines to address specific variants, as well as the timing and populations of booster doses in the coming months. 

The Icahn School of Medicine at Mount Sinai in the US has started a Phase 1 clinical trial of an investigational egg-based COVID-19 vaccine. The vaccine contains a recombinant Newcastle disease virus that expresses the SARS-CoV-2 virus spike protein, and will be administered to healthy adults previously immunised against COVID-19. It has no adjuvants or preservatives and could possibly offer added immunity against the virus. 

21 March:

AstraZeneca announced today that Evusheld, its antibody-based medicine for the prevention and treatment of COVID-19, retains neutralising activity against Omicron coronavirus variants, including the highly contagious BA.2 sub-variant. This is the first data looking at the impact of Evusheld treatment on "cousins" of the Omicron variant following a recent global spike in cases. The study has yet to be peer reviewed. 

Ivermectin failed to curb COVID-19 hospitalisations in the largest trial of the drug to date. Researchers found the antiparasitic failed to produce better patient outcomes than in the placebo group, looking at factors including hospitalisation rate, extent of symptoms and death rate. One of the study's lead researchers said there was "no indication that Ivermectin was clinically useful" for the treatment of COVID-19. 

Moderna announces a new supply agreement with the Swiss government for seven million doses of the company's COVID-19 booster vaccine, with anticipated delivery in 2023. The agreement also includes the option of an additional seven million doses for delivery in 2023 and 2024. 

18 March:

A study published today by The Lancet explores the Omicron variant's sensitivity to neutralisation, in light of concerns that vaccines may not provide robust protection against the new variant. Researchers found "extensive, but incomplete, evasion of neutralising antibody responses," suggesting boosting with licensed vaccines may be sufficient to raise neutralising antibody titres to protective levels. 

New research, published in Med, has identified a potentially effective treatment for COVID-19 patients with Acute Respiratory Distress Syndrome (ARDS). A clinical study conducted by Irish researchers has found an anti-inflammatory protein, alpha-1 antitrypsin (AAT), reduces inflammation in ARDS patients. The trial will move on to phase 3 and could be an important addition to existing therapeutics, as ARDS treatment options are currently limited. 

16 March:

Pfizer CEO Albert Bourla announces the drugmaker is submitting data to the FDA which outlines the recommendation for a fourth dose of the vaccine it developed collaboratively with BioNTech. While the current levels of protection from the third booster reduces numbers of patients suffering from severe illness or hospitalisation, he advocates that a fourth dose would help to reduce infection.

15 March:

Four leading members of the World Trade Organisation, the U.S., EU, South Africa and India have reached an agreement on a waiver of the Trade Related Intellectual Property agreement for the production of vaccines against the COVID-19 pandemic. This would allow developing countries to permit the domestic manufacturing of vaccines without the consent of the patent holder, a crucial step forward for global vaccine equity.

7 March:

In a paper published by The Lancet today, a study conducted by the CDC into the safety of mRNA vaccines found no link between the administration of the Pfizer/BioNTech or Moderna vaccines and death. Safety data from more than 298 million doses of mRNA COVID-19 vaccine administered in the first 6 months of the US vaccination programme show that the majority of reported adverse effects (92%) were mild and short in duration.

Moderna announce plans to establish its first mRNA vaccine manufacturing site in Africa. The new site will be located in Kenya, and will enable Moderna to produce up to 500 million doses each year for the African continent. Moderna plans to invest up $500 million in this new facility which will focus on drug substance manufacturing in Africa, for the continent of Africa, and could be expanded to include fill/finish and packaging capabilities at the site.

21 February:

Over ten thousand participants from across the UK have now taken part in the NIHR-funded and supported PANORAMIC trial - the world’s largest study into new antiviral treatments against COVID-19 in community, ambulatory care.

The nationwide trial launched in December 2021 to rapidly generate evidence on which of the people suffering with COVID-19 at home and in the community are helped the most by new antiviral treatments - without needing to be treated in hospital. The trial will investigate a range of potentially ground-breaking oral antiviral drugs, which can be safely taken at home by people in at-risk groups (aged 50 or over, or 18-49 with a preexisting condition), in the early stages of infection.

The first antiviral drug currently being assessed through the platform trial is molnupiravir, which has already been shown to be safe and effective through smaller-scale trials. The study is expected to show how well molnupiravir works in a predominantly vaccinated population, as well as its cost effectiveness.

11 February:

The FDA issued an emergency use authorization (EUA) for a new monoclonal antibody for the treatment of COVID-19 that retains activity against the omicron variant. The EUA for bebtelovimab, manufactured by Eli Lilly, is for the treatment of mild to moderate COVID-19 in adults and pediatric patients with a positive COVID-19 test, and who are at high risk for progression to severe COVID-19, including hospitalization or death, and for whom alternative COVID-19 treatment options approved or authorized by the FDA are not accessible or clinically appropriate. 

WHO adds Tocilizumab, a monoclonal antibody, to its list of prequalified treatments for COVID-19. To date, six COVID-19 treatments have been prequalified by WHO. Tocilizumab, which is manufactured by Roche and has been authorised mostly for the treatment of arthritis, is a monoclonal antibody that inhibits the Interleukin-6 (IL-6) receptor. When given intravenously, it has been shown in clinical studies to reduce death in certain patients with COVID-19 who are severely ill, rapidly deteriorating and have increasing oxygen needs. In the largest clinical trial, Tocilizumab also reduced patients’ time in hospital.      

The patent for Tocilizumab has expired for most of its uses, which means there should be no intellectual property barriers for this particular IL-6 blocker. However, Tocilizumab is in short supply globally and is an expensive product – reportedly around USD 500-600 per single dose. WHO and partners are currently discussing lower prices and improved access in low- and middle-income countries with the producer, Roche.

9 February:

Glenmark Pharmaceuticals Limited – a global, innovation-driven pharmaceutical company and Canadian pharmaceutical company SaNOtize Research & Development Corp. announce the launch of its Nitric Oxide Nasal Spray under the brand name FabiSpray® in India; for the treatment of adult patients with COVID-19 who have high risk of progression of the disease. FabiSpray®, Nitric Oxide Nasal Spray, is designed to kill the COVID-19 virus in the upper airways. It has proven anti-microbial properties with a direct virucidal effect on SARS-CoV-2. NONS when sprayed over nasal mucosa acts as a physical and chemical barrier against the virus, preventing it from incubating and spreading to the lungs.

25 January:

• The FDA has revised authorisations for Regeneron’s REGEN-COV and Eli Lilly’s Bamlanivimab and etesevimab COVID-19 monoclonal antibody drugs, in light of new data indicating these treatments would prove ineffective against the omicron variant. Monoclonal antibodies are laboratory-made proteins that mimic the immune system’s ability to fight off harmful pathogens such as the COVID-19 virus, and like other infectious organisms, this can mutate over time, resulting in certain treatments not working against certain variants such as omicron. The US regulator stated that 'The FDA is committed to continuing to review emerging data on all COVID-19 therapies related to the potential impact of variants and revise the authorizations further as appropriate to ensure healthcare providers have an effective arsenal of treatments for patients.'

23 January:

• WHO Europe Director, Hans Kluge, tells news agency AFP that the Omnicron variant has moved the COVID-19 pandemic into a new phase, making it plausible that "the region is moving towards a kind of pandemic endgame." He adds that once the current surge of Omicron currently sweeping across Europe subsides, “there will be for quite some weeks and months a global immunity, either thanks to the vaccine or because people have immunity due to the infection, and also lowering seasonality.”

17 January:

• COVAX, the vaccines pillar of the WHO Access to COVID-19 Tools (ACT) Accelerator, has delivered its 1 billionth COVID-19 vaccine dose following a shipment of 1.1 million COVID-19 vaccines to Rwanda.

30 November:

• Moderna CEO Stéphane Bancel predicts that existing COVID-19 vaccines will be much less effective at tackling the Omicron variant than earlier strains of coronavirus and warns it will take months before pharmaceutical companies can manufacture new variant-specific jabs at scale, according to the Financial Times. He says the high number of Omicron mutations on the spike protein, which the virus uses to infect human cells, and the rapid spread of the variant in South Africa suggest that the current crop of vaccines may need to be modified next year.

29 November:

• The World Health Organisation recommends priority actions to nations to enhance readiness and prepare response to the newly discovered and highly transmissible Omicron variant. These include ensuring early warning systems are in place, ensuring mitigation plans are in place to maintain essential health services and necessary health care resources are in place to respond to potential surges. The WHO says countries should also regularly communicate evidence-based information on Omicron and other circulating variants. “The overall risk related to Omicron is considered very high for a number of reasons. First, the global risk of COVID‐19 remains very high overall, and second, there is concerning preliminary evidence on Omicron suggesting, in contrast to previous VOCs, both potential immune escape and higher transmissibility that could lead to further surges with severe consequences,” the WHO says.

28 November:

• In a statement from the WHO, new variant B.1.1.529, now named Omicron, has been designated a variant of concern.
