Which still leaves: Poland, Lithuania*, Estonia, Finland, Belgium, Austria*, Czechia, Slovakia, Greece, Croatia, Hungary, and Romania, all of which are actually 'Mainland EU' as you originally described, still proceeding. So your statement "Mainland EU have stopped using the AZ" is entirely untrue. I am glad we could clear this up.
*Austria and Lithuania, have stopped using one specific batch of AZ but are continuing with other batches.
Just because France may have a stockpile due to poor uptake of the vaccine and an overly complex proceedure to deliver it, doesn't mean the whole of the continent does.
So here is a question, if it was political: based upon AZ being partially a British company, which seems to be what is being alluded to by people on here and Conservative politicians with a known hatred of the EU, then why is Sweden on the list, given that AZ is a joint British-Swedish multinational?
