What kind of medical professionals?
My Wife, a ICU RN+CCRN spent most of her 2020 on the COVID floor. It was pretty brutal for her.
She has coworkers, of equal status, who experienced pandemic alongside her first hand - who were extremely hesitant to get the vaccine. This includes several months after the initial rollout to staff.
I have medical professionals in my family. Your statement sums it up. In my experience, physical/occupational therapists are the most likely to believe in crazy stuff (from a medical standpoint). RNs come next. I'm sure there are people in between on that spectrum, but I don't interact with them much.
