You just confirmed my point. The EU -in contrast to the US and the UK- did not want any exclusivity. They wanted collaboration and a fair distribution of vaccines. They negotiated on a EU level exactly to avoid any nationalistic competition. I am not saying that the US/UK strategy is bad in any objective way. I am just saying that it is the same strategy.
By "fair" do you mean EU countries favoured over the rest of the world? How much have the EU exported? They only house 6% of the world's population, but are keeping something like 75% for themselves, no?
And how much would be the EU's "fair" share of vaccine manufactured in the UK? As they seem to be expecting far more than that 25% for themselves, from their retoric they wanted it "evenly" distributed, i.e. massively in their favour, directly from Ms Von der Leyen's mouth:
“That is the message to AstraZeneca, ‘You fulfil your contract with Europe before you start delivering to other countries’.”
There's nothing "fair" about the EU's distribution of the vaccine, claiming otherwise shows complete naivety or bare faced lying.
