Having a preferential contract with a single supplier is not remotely the same as imposing export controls on every supplier within a territory. The EU is and always has been allowed to source vaccines from the UK and the fact it voluntarily chose not to does not mean it was 'effectively' banned from doing so. The British government spent months and tens of millions of pounds setting up the AZ supply chain while the EU were haggling over its contract. It's not then unreasonable for the British government to require that it has priority on the supply it was instrumental in creating.
