Hello Dr. Bob :) Thank you for answering our questions!!
I received the adult pertussis (I think tdap) vaccine when my daughter was 3 days old. I have been exclusively breastfeeding her since birth. Since I received the vaccine while breastfeeding would my body have built up antibodies against pertussis from the vaccine and then transferred them to her through my breastmilk? If so how effective is this in building up resistance to pertussis? She is 11 weeks and not received the dtap vaccine yet.
Thank you for your response!
