I am 22 weeks pregnant with my 2nd baby and I keep getting worried about pertussis. I am allergic to the tdap vaccine and was told to never get it again. My husband and I rent with my mom and I run a home daycare business with her. Technically I can take off for longer, but my mom can't, so we will still be around kids. What do I do? Has anyone else not or can't get the vaccine?
