So the excretion of drugs and food allergens into milk is impossible? If something enters the blood stream it can be excreted in breast milk.
It’s an incredibly ignorant post. Vaccines have additives. You have to study each additive abd determine whether it can get to breast milk before you reach that conclusion.
No where in the article did it state that the woman was taking drugs or had a food allergy. (In any case, allergens are a separate issue, unrelated to vaccination.)
1) Vaccines are injected into the arm muscle, not the blood.
2) The body is very efficient about destroying foreign proteins and nucleic acids (the vaccine components). In this case, the nucleic acid is messenger RNA which has, at most, a ten hour half life.
3) The immune reaction occurs at the site of injection, in the form of T-cells, B-cells, macrophages, etc., that come to the location in response to the presence of antigen.
4) In the case of vaccination, the challenge is to keep the antigen around long enough for the immune response to occur before the body destroys the antigen.
5) The milk of a vaccinated woman would contain antibody-producing B-cells, which protect the baby against disease. It not only is not harmful for the baby to consume the mother’s B-cells, the benefit that B-cells provide is one of the major reasons to advocate breast-feeding.
