The federal government is being urged to halt trade talks with Brazil after another summer of record-breaking fires in the Amazon rainforest.

Bolsonaro has said, ``No one can force anyone to get a vaccine," adding his opposition to administering vaccines that are yet to be proven on Brazilian soil.

The comments come after the government earmarked millions of dollars for the purchase and future production of vaccinations.

The nation of 210 million people has been reporting an average of more than 1,000 daily deaths from the pandemic since late May and reported 905 for the latest 24-hour period.

A spokesperson for Facebook said the order was "extreme" and threatens "freedom of expression outside of Brazil's jurisdiction," but said the company has agreed to the order.

So far, 16.3 million people have been infected with the virus across the globe while 650,918 people have died, according to a tally kept by Johns Hopkins University.

 Brazilian President Jair Bolsonaro said Saturday that he has tested negative for the new coronavirus, based on a fourth test since he said July 7 that he had the virus.

On Thursday, confirmed cases in Brazil totaled 2,012,151, while deaths numbered 76,688.

The far-right leader said he hasn't experienced serious symptoms of the disease as he isolates at the presidential residence in capital of Brasilia.

The president announced that he had tested positive on Tuesday, and said he was quarantining while also taking the unproven drug hydroxychloroquine.
