Is Tick-Borne 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 Tick-Borne Encephalitis Vaccine. The text below is quoted from that source — it is not our own verdict.

Summary of use during breastfeeding

No information is available on the clinical use of tick-borne encephalitis vaccine during breastfeeding. In general, vaccines given to a nursing mother do not affect the safety of breastfeeding for mothers or infants.[1,2] Because the vaccine is inactivated and contains no live virus, it cannot infect the mother or infant. No non-live vaccine has previously been reported to cause infant adverse effects via breastfeeding.[3] Maternal vaccination with tick-borne encephalitis vaccine is not a contraindication to breastfeeding.

“No published information” means the studies do not exist yet — not that Tick-Borne Encephalitis Vaccine is known to be harmful, and not that it is known to be safe. Your prescriber or pharmacist can weigh your baby's age and whether a better-studied alternative would do the same job. Worth asking before stopping a medicine you need.
