“quote HIPPA etc”
HIPAA
Clinically, from what I've read, HIPAA doesn't apply. Anyone can ask you your vaxx status. That's not a crime. In turn, you're under no obligation to answer them, and that also isn't criminal. It's trouble if your healthcare provider gives out your info without your consent in most circumstances.
I cringe a little when I read the HIPAA posts because they're often off.
