Have you not had to care for confirmed/suspected COVID?To clarify...if there will be airborne goobers and/or blood, I will wear some kind of face protection with eye wear. I haven't worn an N 95/respirator since my vaccination and never have for unknown status for any pathogen. I've no doubt been unknowingly exposed to TB and all kinds of flus. If I'd wear that type of mask after vaccination, it would follow that I ought to wear it long after Covid is gone and I'm not doing that.
I mean, fine if you aren't doing any cases but I find it anecdotally funny that it is anesthesia who I had the most trouble with as far as PPE compliance, COVID infections exposing other staff during this whole thing. I love anesthesia providers (particularly crit care trained), but dang if there aren't some who are just decide they know what is best and they are going to do that despite what anyone else says, and then they are going to play stupid when confronted. "What do you mean I can't have a beard with my N95?" "I need a fit test?" "I need to have both elastic bands on?" Yea I know they weren't ignorant, it sure made for some drama as surgeons and OR staff were unhappy... </general rant, not directed at e-tank>
There is a huge difference in risk stratification working with (infectious disease) sick people vs not sick/screened people. The difference shifts but remains if you are presumed likely immune.
You ought to be wearing airborne protection for any suspected airborne pathogen patient and any or AGP with a suspected droplet pathogen (you can aerosolize flu etc). Vaccines aren't 100% as you well know. You don't go into a disseminated herpes zoster room without PPE just because you had chickenpox as a kid, nor do you go into a measles room without PPE.
Wearing N95 as standard precautions in EMS, well, I never was quite fully onboard with that except in certain situations... but in an airborne pandemic it wasn't a terrible idea either. As we move out of pandemic prevalence levels and mandate vaccinations, I think we can even smartly move away from mandatory airborne precautions for all AGP on low-suspicion unscreened patients.
