Starting February 28th, the federal government will no longer be requiring PCR tests for fully vaccinated travelers entering the country. Those with at least two doses of a COVID-19 vaccine will only need a rapid antigen test, approved by the country they're coming from, within 24 hours of their flight.
Vaccinated travelers can still be selected for a random test when they arrive, but will not be required to quarantine while waiting for the results. The antigen tests are often much less expensive than a PCR test. Unvaccinated travelers will still be required to take a PCR test and quarantine for 14 days upon their arrival.
