Before everyone gets hot and heavy, I am referring to vaccines given to the mother. Mother of 14 month breastfed girl was given MMR and Tetnus vaccines as required to work in son's preschool program. After getting the vaccines she tells the Doctor, "Oh, by the way, I'm breastfeeding. Is this a problem?" The doctor says "Well, just wean."! When the mom asked why she was told because the viruses mutate as your body sheds them and she wouldn't want to infect her baby (who, incidentally, just got her shots). She called me and asked if it was ok to breastfeed. I repeated what I remembered about if the vaccine could be absorbed orally then it would be given orally, otherwise it was deactivated in the gut. I suggested she share the references with the Dr. When I started to look, I only found Lawrences reference to Rubella Vaccine saysing the best time to give it was immediately postpartum. Yaffe & Stark says no info available in breastfeeding. Is there any research on Vaccines and breastfeeding???? How about our pharmacists?? Help please.
