CMV: I see nothing wrong with businesses requiring a COVID vaccine "passport" for entry to ensure guest safety

I recently read about NY's COVID passport, which is to be used by vaccinated persons to show proof of vaccination before being admitted to certain venues, and was shocked to see so many negative opinions. I don't see how having to show that you've been vaccinated is any different than when businesses were taking temperatures before admittance. I honestly don't know how else sports and concert venues, cruises, etc are expected to safely open back up without this until the US has achieved a herd immunity vaccination percentage.

We already have laws preventing discrimination due to medical history, as well as medical privacy laws. Why make an exception for COVID vaccines if not for other things as well (say, other vaccines, STDs, etc)? It leads to a bit of a slippery slope when it comes to people disclosing their private medical information.
