BRUSSELS, June 15 (Xinhua) -- The European Union (EU) has administered more than 300 million doses of COVID-19 vaccines, European Commission President Ursula von der Leyen announced Tuesday on Twitter.
As of Monday, 53.3 percent of the EU adults had received at least one dose, and 353 million doses had been delivered to the 27-state bloc.
"By now, almost a third of all adults in the EU are fully vaccinated," European Commission deputy chief spokesperson Dana Spinant said Monday.
The EU vaccine strategy is based on a portfolio of different types of vaccines. To date, five vaccines have been granted conditional marketing authorization by the European Medicines Agency. Up to 4.4 billion doses have been bought by EU member states through advanced purchase agreements.
Fully vaccinated EU citizens will be able to enter their vaccination data into the EU Digital COVID-19 Certificate. Going into operating on July 1, the health certificate will allow EU citizens to travel without restriction within the Schengen area.
