What is the bigger threat to the health care system?

At the beginning of the Covid epidemic, we were supposed to quarantine to slow the spread so the health care system wasn’t overwhelmed.

Now, vaccine mandates are supposed to keep the health care system from being overwhelmed.

But vaccine mandates are causing nurses and other health care workers to quit.

Are we allowed to ask whether vaccine mandates are causing more stress on the system — through resignations — than the unvaccinated are?

I don’t know the answer, but is anyone looking into this?
