Travellers to the US will no longer have to provide a negative Covid-19 test to board their flights from Sunday, June 12.
The pandemic has "shifted to a new phase" amid wide update of vaccines, effective drugs and immunity induced by infection and inoculation, the Centres for Disease Control and Prevention (CDC) said as it announced the move on Friday.
These factors have caused the risk of severe illness and death in the US to drop, the country's health authority said.
The US travel industry had been calling for fully vaccinated passengers to be exempted from testing rules for some time.
Travellers with their final destination in the US have been required to take a test on the day before travel and were only allowed on board a flight with a negative result.
The rule applies regardless of vaccination status and to both foreigners and Americans.
Those who have recently recovered from Covid-19 and have a note from a doctor or health authority are exempted. There is no testing rule for domestic US flights and mask rules have also been lifted.
The US travel industry had called for an end to testing rules as quickly as possible. Industry firms including airlines, airports, hotel chains cited the economic impact of the measures in a letter to the White House coronavirus response coordinator.
They also pointed to the fact that there was no testing requirement at land borders with Canada and Mexico.
