Moderna Becomes Second Firm To Reveal Positive Results With Nearly 95% Protection In Trials

An anonymous reader quotes a report from The Guardian: More than 1 billion people could be immunized against coronavirus by the end of next year with shots from the first two companies to reveal positive results, after the latest vaccine was shown to be nearly 95% effective in trials. With the US's top infectious diseases official, Anthony Fauci, hailing "the light at the end of the tunnel", the US biotech firm Moderna announced impressive results for its mRNA vaccine on Monday, a week after interim results for a Pfizer/BioNTech vaccine showed 90% effectiveness. The inclusion of high-risk and elderly people in the Moderna trial suggested the vaccine would protect those most vulnerable to the disease, said Peter Openshaw, a professor of experimental medicine at Imperial College London, who described the results as "tremendously exciting." Though it is more expensive, Moderna's vaccine could potentially provide a major advantage over Pfizer's, which requires ultracold freezing between -70C (-94F) and -80C from production facility to patient. Moderna said it had improved the shelf life and stability, meaning its vaccine can be stored for six months at -20C for shipping and long-term storage, and at standard refrigeration temperatures of 2C to 8C for 30 days. Moderna said it could potentially manufacture 1bn doses by the end of 2021, adding to a further 1.3bn from Pfizer/BioNTech in the same timeframe. Both vaccines require two doses and are due to be assessed by regulators in coming weeks. Moderna is planning to apply to the FDA for emergency use authorization in the coming weeks. "The biotech company said it would have 20 million doses ready to ship in the U.S. before the end of 2020 and hoped to manufacture 500 million to 1 billion doses globally next year," reports The Guardian. It's not expected to be available outside the U.S. until next year.
