Covovax trials begin: Serum Institute of India to launch second Covid vaccine

Mar 27, 2021 15:55 IST | By Editorji News Desk

Serum Institute of India could launch another Covid vaccine -- Covovax -- by September this year, its CEO Adar Poonawalla announced on Saturday.

The trials of this second vaccine have already begun in India this week.

The world's biggest vaccine maker developed Covovax in partnership with US-based vaccine developer Novavax, Poonawalla said in a tweet. He added that Covovax has been tested against African and UK variants of Covid-19 and has overall efficacy of 89%.

The vaccine's efficacy was 96% against the original strain, which is the highest so far. However, it dropped to 86.3% against the UK strain and 48.6% against the mutant variant found in South Africa.
