The Centers for Disease Control and Prevention updated its guidance Friday to say fully vaccinated people can travel within the U.S. without getting a COVID-19 test or going into quarantine.

The agency says vaccinated people should still wear a mask and socially distance when traveling.

For international travel, vaccinated people should still get a COVID-19 test before flying to the U.S. and be tested soon after returning.

Unvaccinated people are still advised to avoid unnecessary travel, but get tested before and after if they do.
