Is Haemophilus Vaccines Safe in Breastfeeding

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

Although there is some conflicting information on the effect of breastfeeding on infants' antibody response to type b vaccines, there is no evidence that breastfeeding reduces protection against the disease. 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 the vaccine.[1][2][3] Breastfeeding alone appears to increase antibodies against and reduce the incidence of type b meningitis.[4][5][6] Breastfeeding also appears to reduce infant side effects associated with routine childhood immunization. Breastfed infants should be vaccinated according to the routine recommended schedules.

Breastfed infants are less likely to have fever[8] and may be less likely to experience anorexia and reduced energy intake[9] after routine childhood immunization than those who are not breastfed.In 2 studies, breastfed infants had higher antibody titers against type b than formula-fed infants at 7 and 12 months of age after vaccination with a type b conjugate vaccine.[1][10] In another study, infants breastfed for longer than 90 days had a better antibody response to the vaccine at 13 months of age than those breastfed less than 90 days.[11]In a study of 408 infants immunized with type b polysaccharide-tetanus toxoid conjugate vaccine, no difference in antibody titer was observed at 7 months between infants breastfed for less than 4 weeks and those who were breastfed for 24 weeks or more. Likewise, no difference in antibody response was found when infants were grouped by breastfeeding less than 1 month or greater than 1 month.[12] Another study of 252 infants who each received one of 4 type b vaccines found no difference in antibody titers among those who were breastfed and those who were not.[13]Among 272 infants who were vaccinated with Hib PRP-OMP vaccine at 2 and 4 months postpartum, 101 were breastfed and 171 were formula fed. Of the breastfed infants, 79% were breastfed at least 80% at 7 weeks and 59% at 7 months of age. Breastfed infants had lower IgG titers than formula-fed infants at both 7 weeks and 7 months of age. Although the difference was statistically significant after adjustment for confounding variables, no invasive type b infections occurred in any of the infants in the study.[14]
