TDAP vaccine

My doctor sent me in a prescription to go take my TDAP vaccine. I understand that it is important and I’m having an October baby so it will start to get a little chilly out and I definitely don’t want her to get the whooping cough. So I decided to get the shot. Well my SO he’s all like “wait til next appointment and I’ll ask if it’s actually recommended or if it’s required” I told him it’s basically required every pregnant women gets it and he’s so nervous and scared for me to get it. Anyone else’s SO did the same?
