Looks like she got her appt and had her shot administered at a shot center just like any other person would.
Problem for you is, she's probably much more informed than any normal person.
Lot's of experience here with shitheads trying to be doctors on the internet. If you've ever been long-term ill , medical staff, as they prepare you for release, explain to you what you'll hear from the Dr. Karen's and other assorted dipshits when you get back into daily life. It's so predictable it's a fucking joke.
If you don't want the shot, don't get it. No problem with not getting the shot. The problem is not getting the shot, and for some reason, trying to convince everyone that you're right without any bona fides to sauce it up with.
