Brazil announces ‘fantastic’ results for Chinese-made COVID-19 vaccine.
Brazil, with more COVID-19 cases than any other country after the United States and India, is on the verge of having its first authorized vaccine for the pandemic disease. At a press conference today, Brazilian researchers reported that a vaccine made by a Chinese company, Sinovac, was safe and had 78% efficacy in preventing mild cases of COVID-19 in a study of more than 12,000 health care workers. It also completely prevented moderate and severe illness caused by SARS-CoV-2 infections, the team said. “The result we are seeing today is fantastic,” Rosana Richtmann, a physician from the Emilio Ribas Institute of Infectious Disease, said at the press conference.
