A friend I grew up with, he was our class valedictorian and one of the smartest people I have ever met, ended up a pediatrician living in the next town over from me. (small world)
We connected on FB and have had lunch a few times to catch up, and vaccination was a topic we talked round about when the Ebola scare was going on.
He won’t accept new patients whose parents refuse immunization, period. Didn’t go into great detail at the time but the head shaking disgust was pretty clear on his face talking about it though.
