I was vaccinated outside the U.S. Does this mean I am fully vaccinated after 14 days?

An individual is considered fully vaccinated 14 days after the second dose of a two-dose vaccine or the first dose of the Johnson & Johnson vaccine. The 14 days is the standard used by the World Health Organization (WHO) and the Centers for Disease Control and Prevention for vaccines with an Emergency Use Authorization or Emergency Use Listing. See the WHO’s COVID-19 Vaccine updates for more information on Emergency Use Listings.

Beginning November 8, 2021, F-1 and J-1 nonimmigrant student visa holders are required to show proof of being fully vaccinated in accordance with CDC guidance before flying to the United States. Learn more.
