I really think this is a huge danger. We are getting the vulnerable into enclosed spaces for 15mins minimum, sometimes much longer, with no real idea if someone in the room (including staff) have the virus. We know the main transmission happens via aerosol transmission. https://twitter.com/KitsonJ1/status/1344995857725337600
Would be horrendous to catch the virus and end up in hospital as a result of queuing for the vaccine - we should be vaccinating *outside* as much as possible, and if it is snowing/raining doing the vaccinations in cars for those who really can't stand the cold.
NHS staff might not want to spend the vast majority of the day outside, but this is a trivial concern compared to people catching the virus in waiting rooms. Pay them a bonus for doing the vaccinations outdoors, and tell them to put a coat on.
This is a must read article. The simplest way to get around the problem is to do vaccinations outside, but at a minimum open windows and doors, and KEEP them open. https://english.elpais.com/society/2020-10-28/a-room-a-bar-and-a-class-how-the-coronavirus-is-spread-through-the-air.html
This paper (via @salonium ) is also clear that indoor transmission is something that has to be taken incredibly seriously - and I'm skeptical a national programme of putting millions of people indoors next to people not in their household bubbles does. https://onlinelibrary.wiley.com/doi/10.1111/ina.12766
