Every vaccine has carried some level of risk. I do think attitudes on that risk have changed over time though.
(I have a relative who was in the first trials of polio vaccination, and I asked her if there was the same kind of reluctance to get it we were seeing with COVID. She smirked and said "Well, let me think... I was in private school, and we were having an indoor play day that day... Indoor because the plane was gonna fly over to spray the DDT and they didn't want us to get directly dusted... Anyway, no, all our parents wanted us to get it because they all personally knew someone, or someone who knew someone, in an iron lung and didn't want that for their kids").
"Get the vaccine to reduce your symptoms or I'll fire you incase it kills you!"
It's not like the vaccine prevents spread to other coworkers, why require it?
Everyone has a different health risk, let them decide whether they can weather a certain viral load.
That is, unless, you have a vaccine that can actually prevent trasmission.
Some of them… well, what an amazing coincidence really!
