In Brazil, researchers say China’s Covid-19 vaccine is just 50.4% effective

CoronaVac, the Covid-19 vaccine developed by China’s Sinovac Biotech, was found to be just 50.4% effective in a Brazilian trial, much lower than 78% as touted earlier. Brazil’s Butantan Institute, which was the first to complete late-stage trial of the vaccine, said the vaccine’s overall efficacy rate fell to 50.4% when including ’very mild’ cases that did not require medical assistance.
