In light of the ongoing problem with measles outbreaks some mothers who did not have their vaccinations as children may now be looking at protecting themselves and hence their babies who are too young to be vaccinated.

Breast-feeding is not a contraindication to MMR immunisation.

MMR vaccine can be given to breast-feeding mothers without any risk to their baby. Very occasionally, rubella vaccine virus has been found in breast milk, but this has not caused any symptoms in the baby (Buimovici-Klein et al., 1997; Landes et al., 1980; Losonsky et al., 1982). The vaccine does not work when taken orally. There is no evidence of mumps and measles vaccine viruses being found in breast milk.
