American tourists who have been fully vaccinated against Covid-19 will be able to visit the European Union over the summer, EU Commission President Ursula von der Leyen told The New York Times on Sunday.

The fast pace of vaccination in the United States, and advanced talks between authorities there and the European Union over how to make vaccine certificates acceptable as proof of immunity for visitors, will enable the European Commission, the executive branch of the European Union, to recommend a switch in policy that could see trans-Atlantic leisure travel restored, von der Leyen said in the interview.

Von der Leyen did not offer a timeline on when exactly tourist travel might open up or details on how it would occur. But her comments are a top-level statement that the current travel restrictions are set to change on the basis of vaccination certificates, the report said.

“The Americans, as far as I can see, use European Medicines Agency-approved vaccines,” she added Sunday in an interview with The Times in Brussels. “This will enable free movement and the travel to the European Union.”

“Because one thing is clear: All 27 member states will accept, unconditionally, all those who are vaccinated with vaccines that are approved by E.M.A.,” she added. The agency, the bloc’s drugs regulator, has approved all three vaccines being used in the United States, namely the Moderna, Pfizer/BioNTech and Johnson & Johnson shots,” von der Leyen added.

She noted that the United States was “on track” and making “huge progress” with its campaign to reach so-called herd immunity, or the vaccination of 70 per cent of adults, by mid-June.

Ursula von der Leyen added that resumption of travel would depend “on the epidemiological situation, but the situation is improving in the United States, as it is, hopefully, also improving in the European Union.”
