Brazil OK’s clinical tests for homegrown COVID vaccine Butanvac
Brazil’s health regulator Anvisa on Wednesday authorized Phase 1 and 2 clinical tests to be carried out on volunteers for the Butanvac vaccine developed by Sao Paulo’s Butantan Institute biomedical center.
The tests for the two-shot vaccine were initially authorized for 400 volunteers, but will later involve an expected total of 6,000 volunteers aged 18 and over, Anvisa said.
