The Brazilian National Health Surveillance Agency (Anvisa) received a request for the emergency approval of Chinese-made coronavirus vaccine CoronaVac on Friday. The petition was filed by São Paulo’s Butantan Institute — which carried out CoronaVac clinical trials in Brazil — following a deal with the federal government for 100 million doses.
Anvisa officials say clearance could come within ten days — but the agency may extend the deadline if further information is necessary.
