The United States is set to end its COVID-19 vaccination requirements for international travellers and federal workers when the coronavirus public health emergency ends, the White House says.

In February, the US House of Representatives voted to lift the requirement that most foreign air travellers be vaccinated against COVID-19, one of the few remaining pandemic travel restrictions still in place.

The Biden administration last June dropped its requirement that people arriving in the US by air must test negative for COVID but kept in place Centers for Disease Control and Prevention (CDC) vaccination requirements for most foreign travellers.

The rules barred Serbian tennis star Novak Djokovic from taking part in some US tournaments because he is not vaccinated against COVID-19, but from May 12 he could freely enter and play in major tournaments such as the US Open.

The Homeland Security Department also said from May 12, it will no longer require non-US travellers entering the US via land ports of entry and ferries to be vaccinated against COVID-19 and provide proof of vaccination upon request.

The Biden administration’s rules imposed in September 2021 requiring about 3.5 million federal employees and contractors to be vaccinated or face firing or disciplinary action have not been enforced for more than a year after a series of court rulings.

A federal appeals court in March upheld a decision blocking enforcement of the employee vaccine requirement.

The White House told federal agencies in October 2022 not to enforce the contractor vaccine requirements even after a nationwide injunction was lifted.

The Health and Human Services Department said it will start the process to end vaccination requirements for Head Start educators and government-certified healthcare facilities.
