But it is, even amongst NHS staff, only half of the nurses my missus works with have had the Pfizer, specifically for this reason, they are waiting for the AZ vaccine. It's a think, a quite sizeable thing. So much so nearly all the Admin Staff who weren't meant to get it yet that want it have had it and there's talk of a family of staff scheme starting this week (my names down)
Granted, they aren't all doing it for patriotic reasons, some may well have other reasons but there are definitely lots of people holding off until they can get the AZ one. Bearing in mind that these nurse also happen to be the school immunisation teams they know a thing or two about vaccines but it isn't the storage thats bothering them, its the new tech vs old modified tech thats bothering them
