Fear of pertussis (whooping cough)

Co
I am 34 weeks pregnant and scared to death over pertussis. Unfortunately, I am unable to get the shot due to being highly allergic. I run a home daycare with my mom, kids age range (infant-10 years). And my home is the daycare. All of our kids are vaccinated (they have to be per COMAR and we have their records) I guess with being a mom I worry and I really don't want anything to happen to my baby. I have been trying to look at my States stats on it, but can't find it.
