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 has said.

In an interview, Senator Renan Calheiros said it is too early to say if Bolsonaro had committed any criminal offense in his management of the public health crisis, and that more investigation is required.

“I think everything points in that direction,” Calheiros said, regarding Bolsonaro's preference for herd immunity.
