The study will involve the city of Serrana, in the southeastern State of Sao Paulo, the research institute said "The entire adult population, estimated at 30,000 people, will be immunized in three months, in an unprecedented action," the Butantan Institute wrote via Twitter on Wednesday.More Related News
