SAO PAULO (Reuters) - Brazil has gathered enough infection data from a late-stage trial of an experimental COVID-19 vaccine developed by China’s Sinovac Biotech and expects to have interim results on its efficiency in early December, trial organizers said on Monday.
Dimas Covas, director of Butantan biomedical research institute that is running the late-stage trial of the Sinovac vaccine in Brazil, said it now has 74 confirmed cases among its trial participants, above the 61 initial milestone set for interim efficiency analysis.
