The new vaccine shall be launched under the brand name of Covovax, which SII is manufacturing in partnership with Novovax.

The vaccine was earlier expected to be launched in June, but Serum’s CEO Adar Poonawalla had said in March that a temporary US ban on exports of critical raw materials could limit the production of coronavirus vaccines such as Novavax.
