Is it safe to breastfeed if I have hepatitis B? Yes. To make sure it is safe, your baby should get two injections when they are born. Your baby has these injections within the first 12 hours. One injection contains immunoglobulin. These are antibodies that help the body fight the virus. The other injection is baby's first hepatitis B vaccine. All babies get this vaccine, even if their mother doesn't have hepatitis B. They'll also get hepatitis B vaccines over the next 6 months. Once your baby has received their immunoglobulin injection it is safe to breastfeed.
