Firstly, the EU have majorly fucked up vaccine deployment, there's no getting around that and no excuse.
But, if people are dying because of a vaccine shortage and vaccine is being sent to us to put into the arms of people very unlikely to die then the vaccine should be rerouted. A few caveats to this, that vaccine should be in people's arms (especially vulnerable people) as fast as possible and not still in shelves. Apparently the US has hundreds of thousands of doses of the AZ vaccine in storage unapproved when it could already be in arms somewhere else in the world.
I also wish the rest of the world would follow our example and delay the second dose to get more people protected. I think the (brilliant) tactic has been overlooked internationally.
This is a global issue and we should take a global view.
So iabu we should get the vaccine we ordered.
Or ianbu they need it more so should deploy it there.
