Breastfeeding after maternal immunisation during pregnancy: Providing immunological protection to the newborn: A review

All of the studies in this review that measured disease specific antibodies in breast milk (n = 8 papers), stressed the beneficial effect of maternal vaccination during pregnancy on the amount of disease specific sIgA in breast milk. Only a few studies demonstrated a potential protective effect, particularly with influenza vaccines. In an era where maternal vaccination is increasingly considered as a valuable strategy to protect both the mother and infant, further research is needed to assess the effect on breast milk sIgA and to understand the potentially beneficial effects to the infant.
