All adult residents or foreign nationals traveling to the U.S. will be required to be fully vaccinated before boarding their flight. This is in addition to the current requirement that travelers show proof of a negative COVID-19 test taken within 72 hours of departure to the U.S. Once the vaccination requirement is put in place, the White House will ease all the country-specific restrictions on international travel that have prevented noncitizens who have been in the United Kingdom, European Union, China, India, Iran, Republic of Ireland, Brazil or South Africa in the prior 14 days from entering the U.S.
U.S. citizens and permanent residents who are not fully vaccinated will still be able to fly to the U.S., but they will see tougher testing and contact tracing protocols. They will need to be tested within 24 hours of boarding a flight to the U.S., as well as undergo testing upon return to the country. It remains to be seen, though, how the federal government will enforce the testing requirement upon return.
The U.S. will accept full vaccination of travelers with any COVID-19 vaccine approved for emergency use by the World Health Organization, including those from Pfizer, Moderna and Johnson & Johnson used in the U.S. Other vaccines are also approved by the WHO and used widely around the world, including from AstraZeneca and China’s Sinovac and Sinopharm, with varying degrees of effectiveness against COVID-19 and its more transmissible delta variant. The WHO is reviewing Russia’s Sputnik V vaccine but hasn’t approved it.
