COVID, like the flu is not something that stops once you get it. I've known people who have gotten it three times now. It mutates and the best way to stop it is immunization and booster shots. I work in a hospital surrounded by nasty, nasty stuff. I work in what might as well be Gehenna. I get all of my shots and I don't get sick.
Yes, some get it again. But some who have the virus and get the vaccine also get it again, since the vaccine is not sterilizing. And the rates of reinfection are actually not that high, though they certainly happen (as
@ThatRobGuy can testify).
Another relative works in daycare. She got it initially. But despite various variants going through the building since, she has not been reinfected, even when working in a room full of kids who had to be sent home when testing positive for COVID.
The reality is that front line workers are going to be exposed in an endemic situation. And with no sterilizing vaccine, preventing transmission isn't possible. And like the vaccine, prior infection helps reduce severity the next time.
So instead of a blanket mandate they need to consider the risk-benefit of repeated vaccine doses for someone who is young, healthy, and already had the virus. As the study in this thread OP shows there can be risks attendant with each dose.
That is even more the case now that the current variants are somewhat more mild.
Anyone who cares for the sick and refuses to get vaccinated ought to be fired. I am DONE dealing with dead patients and critical results. Even if you have antibodies and you can still be a vector.
There is no sterilizing vaccine. Anyone, even the vaccinated, could be a vector.
And since we are giving opinions I would say health officials who remove informed consent for a non-sterilizing vaccine should be fired.
I would not say that it made sense to fire someone during the Delta wave who had documented prior infection and ongoing antibodies, but retain someone who had been vaccinated. Studies were showing equivalent or better protection from prior infection on the whole. So it is not a scientific argument to compel someone to get a shot, especially when the vaccine is not sterilizing.
Her company took her back, and she has not made anyone sick, unlike some who were there when she was laid off and had the vaccine, but still spread the virus to the residents. I guess they were still vectors.
