However, Ms von der Leyen added, “we didn’t get anything from the Brits while we are delivering vaccines to them”.

She said the commission had sent a “formal reminder” to AstraZeneca regarding this issue.

AstraZeneca’s coronavirus vaccine is one of three approved for use in the EU.

However, its usage has been overshadowed by several problems, including a slow start, recurring delivery problems and a temporary ban for several days earlier this week in many EU member countries after reports of blood clots in some recipients of the vaccine.

Most countries in the EU have resumed giving AstraZeneca jabs again on Friday as infection numbers spike across the continent.

The Oxford/AstraZeneca vaccine, which is cheaper and easier to store than others, is seen as critical to ending the coronavirus pandemic.
