Breaking: Regulators clear additional batch of CoronaVac doses

The board of directors of Anvisa, Brazil’s federal health regulatory agency, has greenlit the emergency use of a further 4.8 million doses of the Chinese-made CoronaVac in a unanimous decision.

On January 17, the agency had cleared 6 million doses of the CoronaVac which had been entirely produced in China. This new batch, however, was packaged in São Paulo’s Butantan Biological Institute, which presided over the vaccine’s clinical trials in Brazil. 

Anvisa directors reiterated the need for producers to submit additional information on how the vaccine works by February 28 at the latest, which would pave the way for the immunizer’s definitive approval.
