From various statements made between AZ and EU and reading the contract it seems to have gone like this.
EU to AZ we would like to buy XXX amount of your not for profit vaccine please.
AZ - ok that will be XXX cost.
EU - we don't want to pay that much
AZ - well as it's for cost the only thing we could do would be to "compromise" on the manufacturing and supply process to cut costs.
EU - okay we'll do that, but we want to be on the same delivery schedule as the UK.
AZ - erm...we would like to do that for you but the UK are investing more in their supply and manufacturing process so theirs will probably be more efficient and they started this process three months prior to yours. So we cannot guarantee that, we will try our best to meet your requirements but we have previous commitments and therefore can only promise you our best try.
EU - ok have the contracts drawn up.
EU - signs contract.
AZ - we're having some trouble getting the plants upto speed you won't get as many vaccines as you would like but we're working really hard to rectify this.
EU - we want UK manufactured supplies instead then.
AZ - but they're for the UK.
EU - Completely loses their sanity and blames the UK.
Fuck all to do with us.
