China’s Sinovac Covid-19 vaccine has been found to be significantly less effective than previous data has suggested. Brazil’s biomedical centre Butantan Institute, which is running final-stage clinical trials for the vaccine called CoronaVac, released new data on January 12, 2021. It said the vaccine has an efficacy rate of 50.4 per cent, a figure way lower than the 78 per cent suggested by data released one week earlier by the São Paulo-based institute. The World Health Organization requires all vaccines to have at least 50 per cent efficacy.
