Vaccinated passengers will be able to enter the US from the UK and EU from November onwards, Sky News understands
The new rules would be part of broader policy changes for international travel.
Under the previous policy, only American citizens, their immediate families, or green card holders could enter the US from the UK or EU.

The US also banned travel for anyone who had been in China, Iran, Brazil, South Africa, or India, 14 days prior to arriving in the country.
Anyone travelling outside any of these areas had to apply for a visa or Electronic System for Travel Authorisation (ESTA) visa waiver to enter or transit the US as a visitor.
