My friends husband took the 3rd shot after having Covid against the wishes of his wife. He did it because he asked the advise of a trusted friend who is a “doctor” said he should. Luckily he is ok so far, but how can you help these people? To me that has be the absolute dumbest thing a person can do, there is no getting through to them. Many of them won’t even admit to themselves that vaccine caused their sudden health problems. I understand Dr. McCulloughs frustration.
