Vaccines and donated breast milk-risks to baby?

[Mamatoto2]

I'm in the process of sourcing out donor breast milk for my 9 month-old son who I have to wean due my recent cancer diagnosis. He is not vaxed and I'm not sure the extent to which I need to be concerned about him being negatively impacted by vaccines that the donor mom might receive or vaccines that the donor mom's baby might receive during the course of his/her own breastfeeding. Are there vax that pass through milk? Are there vax-specific diseases that can contaminate milk from a breast that is also being nursed by a recently vaxed child? Is there an appropriate time period following a particular vax that I should avoid milk from the donor mom (following her own vax or her child's vax)?

I'll be x-posting in the breastfeeding forum but thought you mamas might know lots about this too.

Thank you!

You may have to worry about live vaccines which can shed up to 3 weeks. But I am not sure as to how risky that will be. I am immunocompromised myself, and I dont worry about shedding vaccines. Although I am not as compromised as a cancer patient. Chances are the mother has some immunity already to the live vaccines their LO is getting and would not be carriers. I would think the risk is fairly low and I personally would only worry if the mother herself gets live vaccines.

I would be far more concerned with what food/diet the donors are eating. You will have no idea what it was if your child should have a reaction (who it came from and what it was). Next I would worry about the vaccines. If I didn't vac I would not want to risk any thing from sources that you do know, not to mention any other meds the person might be on, I would not even want an aspirin of some herbs.

The only one that would be an issue with breastmilk is rubella. Donor milk banks will not take milk from a mother who has had a recent MMR or monovalent rubella vaccination.

Ok, so one of the donors I spoke with had (she thinks) DTP and a flu vax (new & improved-now with swine flu) at the time of her baby's birth about 3 weeks ago. She wasn't exactly sure which vax it was but she said it was 3 (I asked MMR?) but she said that it was for whooping cough and tetanus so I'm pretty sure that rules MMR out. So would this be comfortable to others or would yo uwant a longer time period for it to work its way through her system and if so how long?
