I have a country doctor (well, rural). He thought she was a quack.
She hopped on the COVID-19 vaccine causes magnetism bandwagon and then when the state board essentially asked her to respond regarding those claims among others, she ran away.
She got what she deserved.
A doctor could say "The vaccine has magnetized my patients" and the medical board would jerk his or her license without ever bothering to say "Prove it...here's a spoon."
It's like the Ivermectin debacle. When doctors have no latitude, they become robots...science stops.
