Pneumococcal Vaccines Levels and Effects while Breastfeeding

Summary of Use during Lactation

The Centers for Disease Control and Prevention and several health professional organizations state that vaccines given to a nursing mother do not affect the safety of breastfeeding for mothers or infants and that breastfeeding is not a contraindication to pneumococcal vaccine. Immunization of the mother during the third trimester of pregnancy markedly increases the amount of pneumococcal antibodies in breastmilk.[1] Breastfed infants should be vaccinated according to the routine recommended schedules.[2][3][4]

Effects in Breastfed Infants

Limited data indicate that breastfeeding can enhance the response of the infant to certain vaccine antigens.[2][4][5][6]

Immunization of pregnant women with pneumococcal vaccine increased the specific secretory IgA content of milk and colostrum.[7][8][9][10][11][12] These antibodies in colostrum help inhibit epithelial adhesion of pneumococci to pharyngeal epithelial cells.[12] Some evidence of decreased pneumococcal disease has been found among breastfed infants of vaccinated mothers.[10] Infants breastfed for longer than 90 days have a better antibody response to some pneumococcal strains in the vaccine at 13 months of age than those breastfed less than 90 days.[13]
