2 billion Covid-19 doses a long haul, but most will be covered by December

SII aims to make 50 million doses of Covovax (the Novavax vaccine) per month at its Pune plant

While two billion doses of Covid-19 vaccines by the end of this year may be difficult, industry and analysts say a significant portion of the adult population can be covered with at least one dose by December.
 
The ambitious ramp-up plans, however, depend on the availability of raw material, the ability to scale up manufacturing drug substances, and forging partnerships to use the “fill-and-finish” capacities to their fullest.
 
The world’s largest vaccine maker by volumes — Serum Institute of India (SII) — is making 70 million doses a month of Covishield and has started stockpiling Novavax vaccines too.
