TDAP/ Whooping Cough Vaccine

Hey, ladies! 
I'm currently 38 weeks pregnant and my doctor mentioned getting everyone who will be around my baby once she's born to get their TDAP shot to prevent whooping cough. Is this necessary? What are your thoughts on this? Will you be asking everybody who will be around your newborn to get it done? TIA, I'm a FTM so I'd love to be better informed about this. I've already gotten it myself when I was 36 weeks, I'm just unsure about how to ask our family to get it done.
