Americans who have been fully vaccinated against Covid-19 will be able to visit the European Union this summer, Ursula von der Leyen, president of the European Commission, said in an interview with The New York Times on Sunday.

“The Americans, as far as I can see, use European Medicines Agency-approved vaccines,” von der Leyen said, according to the Times report. “This will enable free movement and the travel to the European Union.”
