The US CDC website 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 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*

The CDC adds "If you don’t meet these requirements, you are not considered fully vaccinated. 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."

Yes, from 4am on Friday 12th May 2023, there is no longer a requirement to be vaccinated to travel to the US. The Homeland Security has also confirmed from 12th May 2023, non-US travellers can enter from land ports of entry or ferries without having to show proof of vaccination. 

 Here’s the link to apply for an ESTA (Electronic System for Travel Authorization). 

As of 12th May 2023, you will not be required to show your vaccination status to fly to the United States. 

In the unlikely event that you are asked, the USA will accept the NHS COVID pass on a smartphone or printout, and will also accept the European Digital COVID Certificate. Further information on the forms of acceptable proof of vaccination can be found on the CDC Website. Don’t forget to charge your smartphone battery before travelling. 

Please be aware that online check in may not be available for your flight. It is recommended that you arrive to the airport early ahead of your flight to allow extra time for check in, bag drop and security.

The wearing of masks is optional. 

The US removed the requirement for a negative COVID test for entry in June 2022 for most countries. 

If you feel unwell, it is generally advised not to travel.
