Health experts are warning of a new Covid surge Credit: Getty images Brazilian President Jair Bolsonaro never wanted to buy COVID-19 vaccines and originally bet on herd immunity beating the  coronavirus, the senator leading the upper house's inquiry into the government's handling of the crisis said. In an interview, Senator Renan Calheiros said it is too early to say if Bolsonaro had committed any criminal offence in his management of the public health crisis, and that more investigation is required. "I think everything points in that direction," Senator Calheiros said, regarding Bolsonaro's preference for herd immunity. "The president first denied the disease, called it a flu, and then argued against social isolation and lockdown. Then he played down the use of masks and encouraged crowds to gather," he said.
