There are more poliical angles around AZ than just Brexit. Germany has a bunch of elections this year, for example. A lot of our screwed up Covid measures can be traced to a inner-party conflict about the Chancelor candidate for conservative party, Angela Merkel's government party at the moment. The same party that is up to the neck in a corruption sandal over mask contracts, and quite likely contracts for testing its as well.

No idea how the situation in Denmark is, so. Just one example how vaccines are used for political purposes in Germany, the Bavarian Prime Minister, Söder, and one of the two likely candidates for the chancelor candidacy, just placed a pre order for Russia's Sputnik V. The plan is to produce 2.5 millon doses in a plant in Bavaira by June or so. Never mention that Sputnik V has no EU approval, no study was submitted (what was that again with "faulty" AZ data?) and by June Germany will get up to 260 million doses the EU contracts.

EDIT: I read the 260 million in an article. Numbers from Statista don't back that up. And the EU isn't publishing any schedules. The supply chain guy in me is crying for a year now, first masks, now vaccines. Really frustrating. I really have to get a new job, right I have too much time on my hand it seems...
