The decision to suspend Sinovac Biotech Ltd.’s coronavirus vaccine trials in Brazil’s largest state has baffled local researchers and prompted speculation that the move could be political.
Sao Paulo’s Instituto Butantan, which partnered with Sinovac to produce the vaccine locally, said there’s no relation between an incident with a volunteer and the shot. The health agency Anvisa, which made the decision, didn’t consult with researchers beforehand, Dimas Covas, head of the institute, said at a press conference Tuesday.
