The EU will prevent future exports of AstraZeneca Covid-19 vaccines leaving the bloc unless the drugmaker significantly steps up its supply efforts, European Commission chief Ursula von der Leyen warned on Monday.

Von der Leyen also accused the Anglo-Swedish pharmaceutical giant of so far delivering less than 10 percent of the EU’s agreed number of doses of the vaccine it developed in partnership with Oxford University.

“AstraZeneca must increase its efforts. Otherwise we cannot allow exports,” von der Leyen said during interviews with German media on Monday.

She said that AstraZeneca had not explained why it is able to supply Australia with vaccines, but not the EU’s 27 member states. (RT)
