I know Reddit loves to make fun of antivaxxers, but I'm legitimately wondering about this one. 



My father has really put up a stink about getting Tdap (Whooping Cough booster) because he doesn't want to put that "poison" into his body. We then told him that it's his choice, but it's also our choice to not let him see the baby until she can start her immunizations. We've seen a number of babies in our area suffer from whooping cough, and my wife and I promised eachother that we would take every precautionary measure to make sure our baby doesn't get it. It's awful.
