6park.com 6park.com 6park.com 6park.com(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. 6park.com
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. 6park.com 6park.com
