Serum Institute of India (SII) is ramping up production of AstraZeneca's Covid-19 vaccine, aiming to have 100 million doses ready by December for a vaccination drive that could begin across India that same month, Bloomberg reported.

If final-stage trial data show that AstraZeneca's vaccine candidate is giving effective protection from the virus, the Serum Institute of India -- which is partnered to produce at least one billion doses -- may get emergency authorisation from New Delhi by December, said Adar Poonawalla, Chief Executive Officer, SII, in an interview with Bloomberg.
