Tdap vaccine for family?

Melissa
I had a doc appt yesterday and she told me I'd need the Tdap vaccine at my next appt and that my husband definitely needs one as well. She suggested close family members also get one if they're going to be around the baby a lot. I put it out there and everyone is kind of making me feel like I'm overreacting and I don't think they'll get it done. Anyone else hear of this or asking family members to get it done?
