Vaccinated travelers coming from the U.S. can still enter France without a pre-departure Covid-19 test.
Previously, France was allowing unvaccinated visitors from the U.S. to present a negative PCR or rapid antigen test conducted within the 72 hours prior to departure.
Also, for example, as of Sept. 15 Austria will require unvaccinated travelers to quarantine for 10 days. Vaccinated travelers are exempt from the quarantine.
Late last month, the European Union removed the U.S. from its "safe travel" list. The announcement didn't require any EU member country to change its entry rules, but an online infographic shared by the council indicated that the EU continued to support travel by those who are fully vaccinated, suggesting that unvaccinated travelers would likely bear the brunt of any resulting policy changes.
Two weeks after that announcement, most EU countries are open to vaccinated U.S. travelers.
