EU poised to overrule UK in AstraZeneca takeover before VDL's vaccine control demand Callum Hoare Replay Video UP NEXT European Commission President Ursula von der Leyen has reignited demands for Oxford-produced coronavirus vaccines to be diverted from the UK to member states to make up for production shortfalls. It comes after the bloc sparked fury over threats to implement checks on the Northern Ireland border to prevent vaccines produced in the EU from reaching the UK - one of the main stipulations of the Brexit deal. Brussels has questioned whether AstraZeneca had previously shipped European-made doses to fulfill Britain's order earlier this year and is now calling for their factories in the UK to work overtime to meet the bloc's demands - but it is not the first time the pharmaceutical company has faced the possibility of being ordered around by the EU.
