I just had my second child and I refused to give him the Hep-B shot on the first day of his life. The acting pediatrician (not his) asked if I was going to do it "in-office" the following week and I said no. She became visually bothered by this and I told her that I didn't think I could consent for him since I didn't understand the reason for him to get the shot. She said it is without risk and a public health issue.
Last week we went for his first office visit and my son's actual pediatrician explained that public health means that it's good for the population if they get everyone to get it but individually it has no value to him until he's much older and sexually active or sharing needles. Bonkers...
