COVID Vaccine Requirement for Air Travel to United States

Monday, November 22, 2021

On October 25, 2021, President Biden issued a proclamation which, effective November 8, 2021, will lift the four current geographic travel ban restrictions, and replace them with a global requirement that "noncitizens who are nonimmigrants" (almost all visa categories except permanent residents) traveling to the United States by air from any part of the world establish that they are fully vaccinated, with some limited exceptions.

All air travelers will also continue to have to show results of a negative coronavirus test performed on a specimen taken during one to three days preceding their flight's departure from a foreign country traveling to the United States, in addition to proof of vaccination. Details about how far in advance of flight the test must be performed can be found on the CDC webpage.

Meaning of "fully vaccinated"

The CDC webpage Requirement for Proof of COVID-19 Vaccination for Air Passengers describes the meaning of "fully vaccinated" for this purpose:

You are considered fully vaccinated:

  • 2 weeks (14 days) after your dose of an accepted single-dose COVID-19 vaccine.
  • 2 weeks (14 days) after your second dose of an accepted 2-dose series COVID-19 vaccine; or
  • 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 considered fully vaccinated.

*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."
