In Brazil, the vaccine will be produced by the Butantan Institute, which is linked to the São Paulo government and also coordinates CoronaVac tests in the country.
When making the announcement of the interruption of studies, Anvisa cited a “serious adverse event”, but did not give details about the specific reason that motivated the suspension.

According to the World Health Organization (WHO), there are currently ten vaccines in the third and final stage of human testing; one of these immunizers is CoronaVac.
Before being released to the population, a vaccine must go through three stages of clinical trials that prove its safety and effectiveness. At each stage, more volunteers are recruited and the researchers analyze the test results to ensure that the immunizer can be licensed.
Anvisa was notified in early November
According to the director of Butantan, Dimas Covas, Anvisa was notified on November 6 about the adverse event that involved the volunteer in the CoronaVac tests.
“We are facing a serious adverse event that is not related to the vaccine. I repeat: a serious adverse event that is not related to the vaccine. This information is available to Anvisa from day 6, when the serious adverse effect was reported. “Covas said.
The director of Butantan criticized the behavior of the agency and the way the institute received the news of the interruption of the tests.
“On the 6th, Anvisa received a document that said: ‘Look, a participant in the clinical study had a serious adverse event not related to the vaccine.’ Point. What is expected of such a statement? ‘Look, okay, let’s evaluate, let’s get together, let’s see what were the causes of this adverse event, if you’re saying it has nothing to do with the vaccine, let’s find out,’ “he explained.
“This is what we hope for. Is this what happened? No. I mean, this referral was made on the 6th. Yesterday the 9th, at 8:40 pm, they sent an email to Butantan saying that there would be a meeting today for discuss the serious adverse event. But at the same time, he announced the suspension of the study. Eight forty at night, 8:40 pm, 20 minutes later this news was on the national network. 20 minutes later we were notified by email, the news it was on national television. ”
