The World Health Organization (WHO) last week issued an emergency use listing for the Covaxin COVID-19 vaccine, developed by Indian pharmaceutical company Bharat Biotech, making it the eighth vaccine to receive WHO authorization. Covaxin, which is formulated from an inactivated SARS-CoV-2 antigen, was found to be 78 percent effective against COVID-19 of any severity 14 or more days after the second dose. WHO review groups determined the vaccine meets standards for protection against COVID-19, with benefits far outweighing the risks, and recommended it be used in two doses with a dose interval of four weeks for people 18 and above. The WHO approval makes Covaxin eligible for distribution through the COVAX vaccine-sharing facility, and the vaccine’s easy storage requirements make it especially suited for global distribution.Merck’s oral COVID-19 treatment, molnupiravir, received approval from its first regulatory body Thursday when the UK Medicines and Healthcare products Regulatory Agency authorized its use for individuals with mild to moderate COVID-19 and at least one risk factor for developing severe illness. The treatment—the first antiviral medication for COVID-19 that can be taken as a pill rather than injected or given intravenously—cut the risk of hospitalization or death by about half in clinical trials. Given twice a day, starting within five days of symptoms developing to be most effective, the pill targets an enzyme that the virus uses to replicate, preventing it from multiplying—an approach that should make the treatment equally effective against new variants of the virus as it evolves, according to Merck.On Friday, Pfizer released results from a late-stage clinical trial of its antiviral pill to combat COVID-19 showing it to be highly effective at preventing severe illness among at-risk individuals who receive the drug shortly after the onset of symptoms. The pill cut the risk of hospitalization or death by 89 percent when given within three days of exhibiting symptoms, according to data from the trial, which an independent board of experts recommended be stopped early because the drug’s benefit to patients had proved so convincing. Pfizer plans to submit the data as soon as possible to the US Food and Drug Administration to seek authorization for the pill to be used in the United States.

Molnupiravir, an easy-to-take pill, reduced hospitalizations and deaths by half among higher-risk COVID-19 patients diagnosed with mild to moderate illness in a global clinical trial. The agreement is the first public health license for a COVID-19 treatment or vaccine, allowing the medicine to be produced by all capable manufacturers—once the drug receives regulatory approval—to expand the drug’s availability, widen its manufacturing base, and potentially push down the price. Merck has applied to the US Food and Drug Administration for emergency use authorization, and the European Medicines Agency recently began a rolling review of the drug.The Access to COVID-19 Tools Accelerator (ACT-A) on Thursday launched its new strategic plan outlining a focus on addressing access inequities to tools in underserved areas. Over the next year, ACT-A—a global partnership set up to accelerate the development and delivery of COVID-19 tests, treatments, and vaccines—will aim to support low- and middle-income countries in vaccinating 70 percent of their populations, increasing their testing rates to at least 1 per 1,000 people per day, and treating up to 120 million COVID-19 cases through deployment of existing treatments and enabling access to new therapies. The plan outlines a required budget of $23.4 billion between now and September 2022, including $840 million for research and development.Inexpensive drug fluvoxamine could reduce hospitalization in adults with severe COVID-19, according to research published Wednesday in The Lancet Global Health. The findings, based on a clinical trial in Brazil evaluating high-risk, symptomatic adults who had recently contracted COVID-19, showed participants were less likely to require hospitalization or an extended emergency room stay when given a 100-milligram dose of fluvoxamine twice daily for ten days. Fluvoxamine is commonly prescribed to treat depression and obsessive-compulsive disorder and is known to reduce inflammation, which COVID-19 can cause throughout the body. The study findings, part of the larger TOGETHER Trial aiming to identify repurposed therapies effective against COVID-19 disease progression, have been shared with the World Health Organization and the US National Institutes of Health.
