Lets not pretend the eu are using as much az as they have ordered die to the fact mostly only used on over certain ages , so they don't need it all and they can't blame some of the early failures all on Az , they need to accept they were a bit late to the game as well .
Untrue.
As an example, Spain has administered approx 80% of the 3.815.500 AZ doses it has received (as of last week)
241 of those are second doses, so another 3,815,259 doses will be needed just to complete the vaccination cycle of people who have already had it. Allowing for 20% stockpiled, still over 3 million doses will be needed from around the end of next month when the 12 week mark rolls around, just for the second doses. And there are still many first doses to give to people from 55-70.
It is needed.
