The European Union’s Health Commissioner says AstraZeneca’s delays in supplying its Covid-19 vaccine to member states are “not acceptable.”

“There is a problem on the supply side. Last Friday the company, AstraZeneca, surprisingly informed the Commission and the European Union member states that it intends to supply considerably fewer doses in the coming weeks than agreed and announced,” the European Health Commissioner Stella Kyriakides said during a news conference in Brussels on Monday. “This new schedule is not acceptable to the European Union.”

“The European Union has pre-financed the development of the vaccine and its production and wants to see the return,” she also said, adding that the bloc wants to know how many doses the company has produced, and who they’ve been sold to.

Kyriakides went on to say she’d written to AstraZeneca over the weekend, seeking clarification, and that the issue was again discussed between member states and the company during a joint steering board. A second meeting is scheduled for later today because according to the EU Health Commissioner, AstraZeneca’s answers “have not been satisfactory.”

“The European Union wants the ordered and pre-financed doses to be delivered as soon as possible, and we want our contract to be fully fulfilled,” she said.

The European Union purchased 400 million doses of the Oxford/AstraZeneca vaccine for its member states. The vaccine is in the final stages of approval with the European Medicines Agency and, according to Kyriakides, if all requirements are met, market authorisation could be granted by the end of this week.
