I don't dispute that the vaccines may be effective in reducing hospitalizations & deaths from Covid but that's a separate question from whether and how much they reduce transmission.

I know your entry to the conversation was about transmission, but the broader context here seems to be about hospital staffing, which would make hospitalisation vs cases the more useful question.

Not sure I understand your point? Are you saying that the capacity gains from preventing the marginal addition to ICU occupancy of unvaccinated nurses who become sick and need hospitalization will outweigh the capacity impacts of firing them all?

No- it's about whether a 4% reduction (or 40%, or whatever marginal rate) in transmission is cause for termination, when we know that "compliant” employees, in a near 100% vaccinated population will still transmit the virus.

More so if the argument is that the hospital patient population is especially vulnerable.

We don't even know if the likelihood of transmission is reduced enough to affect over number of transmissions.

The vaccinated and unvaccinated are tested at very different rates, this is comparing apples and oranges.
