(CNN) A leading Chinese Covid-19 vaccine developed by Sinovac Biotech was just 50.38% effective in late-stage trials in Brazil, significantly lower than earlier results showed, according to a statement published by the government of Sao Paulo Tuesday.
While the number exceeds the threshold required for regulatory approval, it falls far below the 78% previously announced, raising questions as to the veracity of the data and fueling skepticism over the apparent lack of transparency regarding Chinese vaccines.
Analysts said the efficacy rate of Sinovac’s Coronavac vaccine in Brazil — the lowest among its global competitors — could affect international confidence in Chinese-made vaccines and hamper Beijing’s effort to repair its image from its early mishandling of the initial outbreak by providing Covid-19 vaccines to developing countries.
