Do I need to show proof of vaccination to travel?

It depends.

Each vehicle adopts its own operational requirements for the care and fights against COVID-19. Currently, only the state of Bahia is obliged to present the voucher at the time of boarding.

In general, to date, the presentation of proof of vaccination is not mandatory for vehicles as a whole, however, some companies may choose to make this requirement.

We recommend that you contact the company responsible for your trip in advance to confirm whether it will be necessary to bring proof of vaccination.

Also pay attention if you go on a tourist tour, as several points throughout Brazil require the document. For safety's sake, if you already have your vaccination up to date, take the document (printed or digital) with you!
