Summary of Use during Lactation

No information is available on the clinical use of monkeypox vaccine during breastfeeding. The Centers for Disease Control and Prevention and several health professional organizations state that vaccines given to a nursing mother do not affect the safety of breastfeeding for mothers or infants and that breastfeeding is not a contraindication to monkeypox vaccine.[1-3] Monkeypox vaccine does not replicate and behaves like a non-live vaccine and non-live vaccines are generally considered to be acceptable during breastfeeding.[4] The US Centers of Disease Control and Prevention states that if monkeypox vaccine is required by the mother, it is not a reason to discontinue breastfeeding.[5]
