This vaccine is commonly given to newborns and infants in many countries (Montagnani 2016, Mittal 2014, Goh 1989). The Centers for Disease Control and Prevention, health experts and several health organizations indicate that vaccines - whether from live attenuated, dead or inactivated microorganisms, or from subunits or toxoids of the same - when administered to breastfeeding mothers do not affect breastfeeding or the safety of mothers or infants and that breastfeeding is not a contraindication for the tuberculosis vaccine (Sachs 2013, ACIP-MMWR 2011, Red Book 2009, Gruslin 2009, Clements 1996, ACIP-MMWR 1989). Breastfeeding increases the immunogenicity of some vaccines (ACIP-MMWR 2011, Pabst 1997), such as BCG when administered on the first day of life (Red Book 2009, Pabst 1989). Breastfeeding women can and should be protected with recommended vaccines like other adults (Red Book 2009, Clements 1996).Newborns and infants should be immunized according to current vaccination schedules, regardless of whether or not they are breastfed (ACIP-MMWR 2011, Red Book 2009).
