Until now, only citizens who had received both doses of the vaccine in the UK were exempt from the 10-day quarantine on their return to England, with the exception of a country considered to be at maximum risk.
The change will mean that any citizen of a fully vaccinated EU or US country will be able to enter England without isolation, whether for tourism, business, visiting family or attending sporting events.
Overall, however, regardless of the country in which it was obtained, quarantine will still have to be carried out when arriving from a territory on the "yellow +" list, such as France, or on red (in this case, at a designated hotel), such as those from several Latin American countries.
All travellers arriving from "green" countries and vaccinated people coming from places in the "yellow" zone, such as Spain, are exempt from isolation, although they must test negative before and after arriving in the country.
In recent days, the travel industry, economically badly affected by the pandemic, has been pressing the Government to relax international travel policy in order to save the summer holiday season.
The measure will, according to the BBC, take effect only in England, with Scotland, Wales and Northern Ireland, which have their own powers, expected to update their travel policies soon.
