Is a mother with hepatitis B surface antigen positive able to breastfeed her child?

Patient's question:

Please ask if the mother has hepatitis B surface antigen positive and can breastfeed the child

Doctor's answer:

Hello! I suggest you check HBV-DNA and get the child vaccinated with the hepatitis B vaccine. After producing antibodies, you can breastfeed. The transmission of hepatitis B through breast milk has not been definitively proven. If you want to ensure safety, it is best to use artificial feeding.
