BRUSSELS (AP) — The European Union's executive arm said Friday it has secured 300 million extra doses of the Pfizer-BioNTech coronavirus vaccine, a move that could ease criticism that the EU's executive arm has not done enough to procure doses for the entire bloc.

Speaking during a news conference in Brussels, European Commission President Ursula von der Leyen said the agreement will double the amount of doses already ordered by the 27-nation bloc.

The EU commission later detailed in a statement that it offered to member states to purchase an additional 200 million doses of the vaccine, with the option to acquire another 100 million doses.

“This would enable the EU to purchase up to 600 million doses of this vaccine, which is already being used across the EU. The additional doses will be delivered starting in the second quarter of 2021,” the EU said. Von der Leyen said 75 million of the extra doses would be available during the second quarter, with the rest being delivered throughout 2021.

Combined with a contract with Moderna for its vaccine, the EU now has the capacity to vaccinate 380 million people, Von der Leyen said, more than 80% of the EU's population.

The EU has sealed six vaccine contracts for up to 2 billion doses, with Moderna, AstraZeneca, Sanofi-GSK, Janssen Pharmaceutica NV, Pfizer-BioNTech and CureVac. But only the Pfizer-BioNTech and Moderna vaccines have been approved for use so far in the 27-nation bloc.

Von der Leyen's announcement came amid growing criticism, notably in Germany, about the decision to let the commission handle vaccine purchases for all EU member nations. Vaccination programs in the EU have gotten off to a slow start, and some EU members have been quick to blame the European Commission for a perceived failure to deliver the right number of doses.

The EU has defended its strategy, insisting that vaccination programs have just started and that large deliveries are foreseen for around April.

“We were faced with a situation where we had huge demand, but the production capacity had not kept pace with that as yet. Now, we have a positive step forward," von der Leyen said.

Amid reports that some EU countries tried to secure separate deals with vaccine manufacturers, von der Leyen also made clear that such negotiations would violate the agreement accepted by all the bloc's members.

“We have all agreed, legally binding, that there would be no parallel negotiations, no parallel contract," she said. “So the framework we are all working in is a framework of 27. Together we are negotiating, together we are procuring and together we are bringing forward this vaccination process."
