EU don't have a leg to stand on legally.
There isn't really any issue as there are naturally delays in production - same as UK had three months ago with AZ, it works out and improves.
EU will get millions of AZ doses in Feb - nothing dramatic will happen out of this other than the EU have shot themselves in the foot. People will be backing out of the room from them in future.
Moderna have delays in Feb for EU.
Pfizer had delays, but now sorted.
Our government don't need to worry as they know what they've signed and they are just trying not to laugh too openly at the tantrum in front of them. Being polite and waiting for it to die down. Parent says chicken pie for dinner, child says No! has a tantrum, rings school and says my parents are treating me terrible and puts a photo on the internet of their chicken pie.
Parent doesn't need to react - it's dinner time and either eat it or not that's what's on the table. Nothing changes from tantrums, does it?
It's all just very, very embarrasing for the EU and no one will trust them again for serious business. Sorry for anyone that thinks this will blow over. The effects won't start to play out for a while yet but the UK will do very well out of internationally and trust our legal system even more than they did previously.
A trading bloc that can retrospectively put rules in place and bad mouth a not for profit vaccine during a pandemic and then publish a contract, not to mention Ireland! None of it is in anyway acceptable - they have embarrassed themselves and exposed their lack of judgment (oh, and planning).
But no it isn't a really big deal - nothing has changed or will change from EU actions over the last week other than they look untrustworthy.
So whoever said why is there anger is misjudging it, it is appalling behaviour and shocking behaviour and that is what people are reacting to. I guess like all bullies they're hoping to make people angry and up the ante every time they don't get a reaction, until they go pop themselves and then they take delivery of their AZ vaccines in Feb(eat the chicken pie).
Embarrasing and shoddy way to treat EU citizens if they were hoping for the vaccine they do/don't want ...hard to know really - tastes good with gravy on.
I'm not worried about my 2nd dose of Pfizer, I guess the EU bullies are hoping we UK citizens are worrying - that's their objection and why it was for UK audience and not EU audience currently. Embarrassing for them, but not surprising - not angry. Think that poster mistakes bit of passion for anger...
