Do not travel internationally until you are fully vaccinated. If you are not fully vaccinated and must travel, follow CDC’s international travel recommendations for people who are not fully vaccinated.

Fully vaccinated travelers are less likely to get and spread COVID-19. However, international travel poses additional risks, and even fully vaccinated travelers might be at increased risk for getting and possibly spreading some COVID-19 variants.

The COVID-19 situation, including the spread of new or concerning variants, differs from country to country. All travelers need to pay close attention to the conditions at their destination before traveling.

CDC will update these recommendations as more people get vaccinated, as rates of COVID-19 change, and as additional scientific evidence becomes available.

Recommendations for Fully Vaccinated People
