The UK got a several-week headstart on the EU, announcing various partnerships, particularly with Oxford/AZ, before the EU even began their process. (Yes, I am aware that purchase orders were signed at different times, but the UK secured funding and supplies back in May last year, when the EU didn't begin its process until June)

Talking about "queue jumping" or "corruption" really seems to be rooted in bitterness or just anti-UK sentiment.
