I was grateful to have AZ and it has had a huge amount of unnecessary bad press. It’s a shame other countries delayed vaccinated people because of this
I made an utter fark up of a posting where I tried to address this point on another thread yesterday so I’ll try and do better with this.
Vaccine procurement was an generally an EU function.
Vaccine programs (logistics, facilities, staff, admin) are OTOH a national issue.
The UK did well by getting it’s AZ order in early.
The UK NHS was by it’s nature/design better to set up to immediately start a mass vaccination campaign.
Neverthless many but not all countries in Europe were only a matter of a handful of weeks (locally less than a month) later than the UK in starting their campaigns, but it took longer to get their campaigns up to the sort of daily rates seen at one point in the UK because of the way their healthcare systems operated….
To conclude and avoid a TL;DR…I suspect the reason for the difference in timing of waves has much more to do with the getting the UK initial order for AZ in promptly and then even more importantly the NHS rather than the well publicised spats and arguments that went on at head of state level.
