The United States will drop a requirement for travellers to test negative for COVID-19 before entering the country.
The change will come into force at midnight on Sunday for all passengers arriving by plane.
Kevin Munoz, the White House assistant press secretary, tweeted that Joe Biden’s work on vaccines and treatments was “critical” to the development.
He said the Centers for Disease Control and Prevention (CDC) will monitor “based on the science and in context of circulating variants” but for now deemed testing was no longer necessary.
Previously fully-vaccinated arrivals to the US could show a negative test result within three days of travel, with non-vaccinated individuals made to test within a day of their journey.
But when the Omicron variant swept the US in November, Mr Biden toughened the rules to require all non-US adults to test within a day.
