Are you fully vaccinated to travel to the United States?
You are considered fully vaccinated:
- 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 receiving the full series of an accepted COVID-19 vaccine (not a placebo) in a clinical trial
- 2 weeks (14 days) after receiving 2 doses of any mix-and-match combination of accepted COVID-19 vaccines given at least 17 days apart*
If you do not meet these requirements, you are NOT considered fully vaccinated for travel to the United States. A booster dose is not required 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 is therefore NOT considered fully immunized for travel to United States.
* The CDC has not recommended the use of primary mix-and-match COVID-19 vaccine 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, the CDC will accept combinations of accepted COVID-19 vaccines.
