Well, Brazil, despite Bolsonaro attempts to let the pandemic runs its course (and killing the projected 2 million deaths if no control measures were taken) is starting to see a downturn in cases, thanks to the vaccination rates gathering pace. The restrictions are much softer now (bars and restaurants - including saunas - can stay open up to 11 pm in São Paulo, the state with most restrictions). Keep in mind the virus is still in circulation, but if you are vaccinated and would use masks in public places , I guess it’s an reasonable risk to travel to Brazil now, and you would not lose much in terms of fun in Rio or SP - unless you would want to engage in crowed parties like the ones in The Week or other pool parties (some can still be found, but “underground”).
