Are You Fully Vaccinated for Air Travel to the United States?
- 2 weeks (14 days) after an accepted single-dose COVID-19 vaccine
- 2 weeks (14 days) after your second dose of an accepted 2-dose series
- 2 weeks (14 days) after you received the full series of an active (not placebo) COVID-19 vaccine in the U.S.-based AstraZeneca or Novavax COVID-19 vaccine trials
- 2 weeks (14 days) after you received 2 doses of any “mix-and-match” combination of accepted COVID-19 vaccines administered at least 17 days apart*
If you don’t meet these requirements, you are NOT fully vaccinated. Keep taking all precautions until you are fully vaccinated.
If you have a medical condition that weakens your immune system or are taking medication that weakens your immune system, you might NOT be fully protected even if you are fully vaccinated. Talk to your healthcare provider. Even after vaccination, you may need to continue taking all precautions.
*CDC has not recommended the use of mix-and-match COVID-19 vaccine primary series. However, such strategies are increasingly common in many countries outside of the United States. Therefore, for the purpose of interpreting vaccination records for travel to the United States, CDC will accept combinations of accepted COVID-19 vaccines.
