PRAGUE — The Czech Republic will allow citizens from its neighboring and some other European Union countries who were vaccinated to travel freely on its territory, starting in mid-May.

Prime Minister Andrej Babis says such a deal also for the Czechs has been negotiated with Austria, Germany, Poland, Slovakia, Slovenia and Hungary. Other countries, such are Croatia and Bulgaria should follow.

The only condition will be that people travel at least two weeks after they received the second shot of a coronavirus vaccine.

The announcement Thursday comes as EU nations are talking about introducing COVID-19 certificates aimed at facilitating travel across the region this summer.
