Brussels on Wednesday demanded that tens of millions of British-made coronavirus vaccines be diverted from the UK to make up a supply shortfall in the jabs in the EU. The European Commission said it was contractually entitled to doses from two UK plants making the AstraZeneca/Oxford University vaccine as its row with the British-Swedish pharmaceutical giant deepened. The British Government said it had a deal with AstraZeneca to supply 100 million doses of the vaccine with agreed delivery schedules. British sources said that, once the UK factories had fulfilled their commitment to Britain, AstraZeneca would be free to supply other countries – something the firm's CEO, Pascal Soriot, confirmed in an interview on Tuesday. But Stella Kyriakides, the EU's health commissioner, said: "We reject the logic of first come, first served. That might work at the neighbourhood butchers, but not on our contracts and not in our advanced purchase agreements." She said there was " no priority clause" in the EU contract between the four production plants in the agreement, two factories in the EU and the two in the UK. "In our contract it is not specified that any country or the UK has priority... This needs to be absolutely clear," Ms Kyriakides said.
