Tdap shots

Is anyone else’s parents or in-laws refusing to get their Tdap? I don’t know why mine (both sides) are so resistant to it. Is it like a new idea that’s so scary to the older generation? It’s making me stress out and since my in-laws are planning to stay with us for 2.5 months, it’s making me worry that 1. they will pass whooping cough to my baby and 2. they’re not going to respect any of my decisions.

Is everyone making their close relatives get the Tdap?
