It is amazing how many people have told me that their doctor (never named) told them not to get the #covid #vaccine because they (the doctor) have been seeing "too many people who got sick from it."

In case you're not a natural skeptic, people who tell you this are lying. They have invented a fictional doctor into whose notional mouth they are putting their own crank opinions. It's a way to commit the "appeal to authority" fallacy even when there is no authority. 

 Also known as "Don't argue with me, argue with my doctor, if you can find them, which you can't, because I made them up, neener neener."
