Updated advice from the Centers for Disease Control and Prevention (CDC) says that Americans who are fully vaccinated against COVID-19 can now travel freely across the U.S.

Travellers must continue to follow other “recommended prevention measures” though, which includes remaining fully masked when on planes, buses and trains.

Citing "recent studies evaluating the real-world effects of vaccination," the health agency suggests that fully vaccinated people can travel "at low risk to themselves." A person is considered fully vaccinated two weeks after receiving the last recommended dose of a vaccine.

Fully vaccinated Americans won’t be required to take COVID-19 tests before or after a trip inside the U.S. and they won’t have to self-quarantine. It’s not yet clear whether they’ll need to show proof of vaccinations to board trains or planes. 

There are currently no federal travel requirements for Canadians (fully vaccinated or not) travelling via plane or car within Canada. However, there may be provincial or territorial rules, depending on the region.
