Is Adenovirus Type 4 and Type 7 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 Adenovirus Type 4 and Type 7 Vaccine. The text below is quoted from that source — it is not our own verdict.
Summary of use during breastfeeding
The adenovirus type 4 and type 7 vaccine is indicated only for military personnel between 17 and 50 years of age. No information is available on the use of adenovirus type 4 and type 7 vaccine during breastfeeding or its excretion in human milk. In general, vaccines given to a nursing mother do not affect the safety of breastfeeding for mothers or infants.[1] However, the product labeling recommends using caution in nursing mothers, because live virus is shed for 28 days following vaccination.

“No published information” means the studies do not exist yet — not that Adenovirus Type 4 and Type 7 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.
