Nov.10 (UPI) — Brazilian officials say they have paused a late-phase trial for a COVID-19 vaccine being developed by China after one of the human test subjects died. Anvisa, Brazil’s national health surveillance agency, said the « severe adverse event » occurred late last month, but didn’t specify the circumstances of the volunteer’s death. Chinese firm Sinovac has been performing the late-stage trial for the potential vaccine, called CoronaVac, in collaboration with the Brazilian Butantan Institute in Sao Paulo.
