Is Diphtheria-Tetanus-Pertussis Vaccines Safe in Breastfeeding

I am a breastfeeding mother and i want to know if it is safe to use Diphtheria-Tetanus-Pertussis Vaccines? Is Diphtheria-Tetanus-Pertussis Vaccines safe for nursing mother and child? Does Diphtheria-Tetanus-Pertussis Vaccines extracts into breast milk? Does Diphtheria-Tetanus-Pertussis Vaccines has any long term or short term side effects on infants? Can Diphtheria-Tetanus-Pertussis Vaccines influence milk supply or can Diphtheria-Tetanus-Pertussis Vaccines decrease milk supply in lactating mothers?

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 DTP vaccine.[1][2][3] Vaccination of pregnant women after 20 weeks of gestation have higher antipertussis IgA levels in their breastmilk. Women who have not received acellular pertussis vaccine with tetanus and reduced diphtheria toxoids (Tdap) previously should be vaccinated with Tdap as soon as feasible in the postpartum period, even if they are breastfeeding, as long as they have not been vaccinated with tetanus and reduced diphtheria toxoids (Td) vaccine within the past 2 years.[4] After vaccination, antipertussis antibodies appear in breastmilk within 1 to 2 weeks; however, conflicting results have been reported on whether breastfed infants are protected from pertussis.[5][6] Breastfeeding appears to reduce infant side effects associated with routine childhood immunization. Breastfed infants should be vaccinated according to the routine recommended schedules. A study of 67 colostrum samples that underwent Holder pasteurization (62.5 degrees C for 30 minutes) found that overall IgG amounts decreased by 34 to 40%. Immunoreactivity against tetanus toxoid decreased by 8 to 20%.[7]

Limited data indicate that breastfeeding can enhance the response of the infant to certain vaccine antigens,[2][3][11] including tetanus toxoid.[12] Breastfed infants are also less likely to have fever[13] and may be less likely to experience anorexia and reduced energy intake[14] after routine childhood immunization than those who are not breastfed. One study of previously vaccinated infants found that at 21 to 40 months of age breastfed infants had higher IgG levels against diphtheria, higher secretory IgA levels in saliva against diphtheria and tetanus and higher fecal IgM against tetanus than formula-fed infants.[15]
