Fully Vaccinated vs. Unvaccinated Requirements
Domestic Travel Requirements
The CDC recommends delaying travel until you are fully vaccinated due to the increased chance of getting and spreading COVID-19.

- Vaccinated Travel- Fully vaccinated travelers do not need to get tested before or after travel unless their destination requires it and do not need to self-quarantine for travel within the United States and U.S. territories.
- Unvaccinated Travel - If you are not fully vaccinated and must travel, follow CDC’s recommendations:
- Get tested with a viral test 3-5 days after travel and stay home and self-quarantine for a full 7 days after travel. Even if you test negative, stay home and self-quarantine for the full 7 days. If your test is positive, isolate yourself to protect others from getting infected. If you don’t get tested, stay home and self-quarantine for 10 days after travel.
- Avoid being around people who are at increased risk for severe illness for 14 days, whether you get tested or not. Self-monitor for COVID-19 symptoms; isolate and get tested if you develop symptoms.
