AstraZeneca said on Friday it would try to deliver 30 million doses to the EU by the end of March, down from a contractual obligation of 90 million and a previous pledge made last month to deliver 40 million doses. Breton told France's Europe 1 radio that the delay was unacceptable, but that for now there were no plans to sue the company. "The good news is that even though there are delays with AstraZeneca we won't be late with our vaccination programme in the first quarter," Breton said. "Pfizer is producing more, much more than planned and is going to deliver more to us," he added. EU leaders have come under criticism for a slower rollout of vaccinations than in other countries such as Britain or the United States due to a longer approval and purchasing process and repeated delivery delays. AstraZeneca's new lower supply target hinges on the bloc's drug regulator approving supplies from a factory in the Netherlands, an internal document showed, Reuters reported on Saturday.
