jas my take on the Austrailian doses are slightly different.
We don't really know the details of the AZ contract with Austrailian. But they had once. Signed before/ after the EU?
Would they have received any doses if the UK AZ sites hadn't stepped in? Did that mean AZ would have had to break contract with Austrailia?
The EU already had doses. Not as many as they would like, but there were no contractual issues..
The UK also had doses, again not as many as they would like but some still.
Az has contracts with customers. It doesn't matter what the current Covid situation is at each customer. The contracts are not designed in this way.
Az needed to get some doses to Austrailia and chose to do this from UK sites. We don't know if the UK govt had prior knowledge of this or not. (I accept they probably did).
The actions of the EU meant that free trade in / out of the EU is no longer possible, at least for AZ. So I wouldn't really expect AZ to import any doses to EU when nothing is coming out.
Ignore the shit coming from the UK govt. That is just political noise.
