Is Japanese Encephalitis Vaccine safe while breastfeeding?
Here is what LactMed, the Drugs and Lactation Database published by the U.S. National Institute of Child Health and Human Development (NICHD), reports about Japanese Encephalitis Vaccine. The text below is quoted from that source — it is not our own verdict.
Summary of use during breastfeeding
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.[1-3]
Effects on the breastfed infant
Limited data indicate that breastfeeding can enhance the response of the infant to certain vaccine antigens.[1,4]
