Brazilian Health Regulator Says Chinese Authorities Have Not Been Transparent About Covid-19 Vaccine

China’s ‘vaccine diplomacy’ efforts hit a snag on Monday as Brazilian health regulator Anvisa said that Chinese health authorities had not been transparent about their experimental Covid-19 vaccines, one of which is currently being tested in Sao Paulo. Anvisa which is assessing the CoronaVac shot developed by China’s Sinovac Biotech said that Brazil was the “international leader” in the evaluation process for the experimental vaccine, Reuters reported. The health regulator noted that while the vaccine has had an emergency use authorization in China since June, the country’s authorities have not been transparent about the criteria used for granting this authorization.
