Is it safe for women who received smallpox vaccine during pregnancy to breastfeed their babies?
Pregnant women should not receive the smallpox vaccine unless they have been exposed to smallpox. If a pregnant woman is vaccinated, she is likely to have been in the very early stages of her pregnancy at the time of vaccination. Her scab will separate from the vaccination site in about three weeks after vaccination, and by the time she delivers her baby, it will be safe for her to breastfeed. Breastfeeding should not take place until the vaccination scab has separated from the vaccination site.
