The Centers for Disease Control and Prevention has updated its guidelines for domestic and international travel.

According to the CDC, those who are fully vaccinated may travel as long as they continue to wear masks and follow other safety protocols. Travelers in the United States who have received either two doses of the Pfizer and Moderna vaccine or one shot of the Johnson & Johnson vaccine at least two weeks ago do not need to get tested for COVID-19 before traveling or self-quarantine when they arrive at their destination.

International travelers arriving in the United States, including U.S. citizens and fully vaccinated people, must present a negative COVID-19 test result taken no more than 72 hours before their flight. They do not have to quarantine when they arrive in the U.S.

Those who are not vaccinated should continue to avoid travel. If you must travel, the CDC says you should get tested no more than 72 hours before your flight and self-quarantine for seven days after you arrive.
