Are You Fully Vaccinated for Travel to the United States?
- 2 weeks (14 days) after your dose of an accepted single-dose 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 accepted COVID-19 vaccine (not placebo) in a clinical trial
- 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 considered fully vaccinated to travel to the United States. A booster dose is not needed to meet this requirement.
A person who has received only one dose of an accepted 2-dose series and has recovered from COVID-19 does not meet this definition, and therefore is NOT considered fully vaccinated for travel to the United States.
*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.
