State media in China performed down the information from Brazil. World Occasions, a state-owned nationalist tabloid, ran a headline that mentioned the Sinovac vaccine was “one hundred pc efficient in stopping extreme circumstances, may cut back hospitalizations by 80 p.c.”
The brand new information may heighten skepticism amongst individuals world wide who’re already cautious of Chinese language-made vaccines, on condition that the nation has a historical past of vaccine high quality scandals. A examine from the Chinese language College of Hong Kong discovered that just 37.2 percent of respondents in Hong Kong have been keen to be vaccinated.
Scientists had already raised questions in regards to the piecemeal means through which efficacy information in regards to the Chinese language vaccines had been launched.
