Do you personally know anyone with Covid conspiracy theories?

Okay, I am hoping this does get out of hand, but I am asking for a reason important to me.
A friend of mine only wears a mask when forced to. She won’t wear them anywhere, even in mandated public places, unless someone says she HAS to put one on.
She is vaccinated. Although now I am wondering if she really is.
I didn’t worry about it too much before, but now with Omicron and how easily it is spread it is worrying me to be around her.
Also, I didn’t know she actually had conspiracy theories about what Covid is and WHY it is.
Any of you going through this?
