Japanese Encephalitis Vaccine Levels and Effects while Breastfeeding

Summary of Use during Lactation

Data concerning the safety of Japanese encephalitis vaccine during breastfeeding are not available. However, the Centers for Disease Control and Prevention and several health professional organizations state that in general vaccines given to a nursing mother do not affect the safety of breastfeeding for mothers or infants. Therefore, breastfeeding is not a contraindication to Japanese encephalitis vaccine in mothers who require it. Breastfed infants should be vaccinated according to the routine recommended schedules.[1-4]
