The EU will restart negotiations over the supply of the AstraZeneca vaccine to Great Britain, and it may reject such requests since the drugmaker did not fulfill its delivery obligations to the EU, Bloomberg reported referring to a senior EU official.

According to the official, the EU has its own contracts with AstraZeneca that aren’t being respected, and all vaccines or separate ingredients being manufactured in European factories will be reserved for local deliveries, RBK writes.

According to the agency’s sources, there are no outstanding requests for UK exports from the production facility in the Netherlands, but if such a request is made, it will most likely be rejected.

The Guardian, citing Airfinity’s forecast, writes that the export ban can cause a two-month delay in Britain’s Covid vaccine program, which will derail the government’s plans to reopen the economy.

At the end of last week, the European Commission President Ursula von der Leyen threatened to ban exports of the AstraZeneca vaccine. “This is a message to AstraZeneca: You fulfill your part of the deal toward Europe before you start to deliver to other countries,” she said. According to von der Leyen, only 30 percent of the doses it had promised were exported to the EU.

The European Commission had stated that it is “tired of being the scapegoat” for the slow rollout of vaccines. Von der Leyen said that AstraZeneca is responsible for organizing the supply of the vaccine, and she criticized the manufacturer for failing to deliver the vaccine.
