The EU's problem is supply rates and that has now cropped up here as well.
Various govs have funded development and manufacture of AZ but not enough to account for supply rates needed which has to be an economic decision. It seems there is some reliance on the Indian Serum Institute and also the need to retest a batch, sort of assumes that the first test didn't go well. Hope they don't go experimental. Vaccine batches are known to suffer from this. In fact before one was even available they mentioned that the amount ordered never arrives, it's always short.
On supply in general there is some poker faced political posturing. Maybe the EU's is the most straight forwards one - exporting stacks all over the place from Germany and in need of more than they are getting. Lots end up here as well.
The hesitancy on AZ started in S Africa. Very small test but those that had it still had symptoms including in some cases shortness of breath. They didn't give precise details. Then not enough older people during testing. Then the clot problem. Pf has some too including a death also sudden deaths. It's tricky as these occur anyway. AZ has more. Neither exceed expected levels so suddenly all start using it again.
It's all just life really. Things happen.
