LJUBLJANA, Slovenia — Slovenia is opening its borders for travelers arriving from other European Union states if they have proof of a COVID-19 vaccination.

The measure which takes effect on Saturday will allow passengers to avoid quarantine requirements and the need for negative coronavirus tests, officials said.

The measure calls for a written proof that two jabs have been administered and that at least 14 days have passed since the second one.

Additionally, all EU citizens who have doctors’ confirmation that they have recovered from the virus in the past six months will also be allowed in without restrictions.

The conditional lifting of the restrictions comes as the Alpine country of 2 million people sees a gradual decrease of coronavirus infections and hospitalizations.

The easing of measures also includes the lifting of travel restrictions within Slovenia and reopening of some schools and most shops.

The 9 p.m.-6 a.m. curfew remains in place.
