Leaders of the EU’s 27 countries met online on Thursday at the start a two-day summit to discuss the pandemic.
“Everyone agreed that we need a digital vaccination certificate,” Angela Merkel, the German chancellor, told reporters after an EU virtual summit.
“This will make travelling within the EU possible and could pave the way for further travel from third countries into the EU.”
However, she said that it could take three months for the European Commission to set up the technology for such documents.
Greece already has digital vaccination certificates. Others such as Denmark and Sweden have talked about developing them.
Greek Deputy Prime Minister Akis Skertsos said that non-vaccinated tourists could also visit Greece this summer.
