Austria and Denmark have teamed up with Israel to produce 2nd generation vaccines against new mutations of the coronavirus.
The alliance, dubbed First Movers Group, comes amid growing frustration over delays in the EU's vaccine rollout. Israel has offered 94 vaccine doses per 100 people compared with just seven per 100 in the European Union.
Austrian Chancellor Sebastian Kurz said it was right that the bloc should procure vaccines for member states but criticised the European Medicines Agency for its slow approval process.
A spokesperson for the European Commission said that member states are free to strike unilateral deals should they choose to.
Chancellor Kurz plans to visit Israel with Danish Prime Minister Mette Frederiksen later this week and confer with Prime Minister Benjamin Netanyahu on vaccine research and production cooperation.
Kurz said on Tuesday that his country and Denmark intend to stop relying solely on the European Union for coronavirus vaccines.
``"We must prepare for further mutations and should no longer be dependent solely on the EU in the production of second-generation vaccines,'' he said.
As part of its strategy, the EU has six contracts for more than 2 billion doses of vaccines, with Moderna, AstraZeneca, Sanofi-GSK, Johnson & Johnson, Pfizer-BioNTech and CureVac.
It is in negotiations with two other manufacturers, but only three vaccines have been approved for use so far in the bloc.
According to the EU, almost 33 million doses of vaccine have been given so far, but only 11 million Europeans have been fully vaccinated. Israel, a country of 9.3 million people, has immunised over half of its population since late December.
Asked whether the move would undermine the EU's vaccine strategy, EU Commission spokesman Eric Mamer said all member states want to continue to be part of it.
"The point is that none of the member states has signaled in any way that they want to receive less doses based on our EU vaccine strategy,``" he said. "What certain member states are looking at is how to prepare the future. We will continue with our vaccine strategy exactly as before and continue to adapt as the situation evolves.``"
Mamer added that, with 27 member countries and a population of 450 million, the EU faces a much bigger challenge than Israel.
"``It's not as if you can take one model and simply stick it on the European Union and say: 'That's what you should be doing,''' Mamer said, adding that each country is in charge of its own vaccine rollout strategy.
Danish Prime Minister Mette Frederiksen said she does not consider the plan to join forces with Israel as a breach of European (vaccine) cooperation.
``"I think we are best off being in European cooperation in the field of vaccines as well,'' she said.
The EU secured vaccine doses for its member states collectively but its members can also decide to negotiate separate agreements as long as they don't compete with the advance purchase agreement sealed by the EU's executive arm.
Several member states have openly criticized the EU for the slow rollout and considered using vaccines developed in China and Russia although they have not been approved by the European Medicines Agency.
On Sunday, Hungarian Prime Minister Viktor Orban got the Sinopharm shot, after recently saying he trusted the Chinese vaccine the most.
In a Twitter post, Kurz praised EU Commission President Ursula von der Leyen for her role in securing vaccine doses for the whole bloc. "``But now we must prepare ourselves in time for further dangerous COVID-19 mutations,'' he wrote.
Kurz added that experts expect annual vaccinations for some six million Austrians.
