Question

The baby, born to a mother who is HbsAg positive and was not injected with Hepatitis B immune globulin at birth, has not been breastfed, and is now three months old. How should this be handled?

Answer

Given your situation, it is recommended to promptly administer the Hepatitis B vaccine to the baby. Since the baby is currently being fed with formula and not exposed to the Hepatitis B virus, it is possible to administer an additional injection of the Hepatitis B vaccine.
