Let's see if it is legal. I'm not sure it is, for example why are they just doing AZ and not Pfizer (despite Pfizer exporting WAY more than AZ)? Also, there are significant unused stockpiles of AZ all over Europe (and very few Pfizer stockpiled). If anything it should be the other way round.

IANAL though.

So so-called "AstraZeneca" vaccine was developed by Oxford University using British government funds (as least in part). They made a deal with AstraZeneca to bring it to the market and insisted that it had to be sold at cost worldwide.

Does that sound like "screwing" anyone?

The EU has handled the pandemic badly overall, and especially the vaccine. They are making noise as a way to distract and deflect and apparently their public opinion is buying it.

They are also complaining about supply of AZ vaccine while, at the same time, trying hard to destroy that vaccine's reputation (so that some people don't want it). This is incomprehensible.

We didn't screw them. They screwed themselves by writing a nonsense contract written by people who don't have a clue.
