Vaccine Reactions and Breastfeeding?

[kamikazismom]

Dr. Bob,

I read your Vaccine Book several months ago, and I just bought the second edition.  I also just watched The Greater Good.  I feel like I have a good understanding of vaccines, their risks and benefits.  My question is, will breastfeeding protect my child from possible vaccine reactions?  Have there been any studies showing that vaccine injured children were not breastfed?  Are the two related?  Thank you!

the only research I know about is that if an infant is nursing DURING the shot, they'll perceive less pain. Also, there's a study that shows one of the vaccines works better in breastfed infants (I forget which one).  Other than that, I don't know of anything regarding severe reactions.
