You are examining a normal term newborn whose mother is hepatitis B virus surface antigen positive. Which of the following protocols is recommended for the child?

Hepatitis B infection is more likely to become chronic when acquired early in life. In 1991, the CDC recommended universal immunization of infants in the United States. The vaccine is given in a three-dose schedule, with the timing dependent on the mother’s hepatitis B surface antigen status. If the mother is hepatitis B surface antigen positive, the first dose of vaccine and a dose of hepatitis B immune globulin must be given within 12 hours of birth. The second dose of vaccine is given at 1–2 months, and the third dose is given at 6 months. For mothers with unknown antigen status, the first dose of vaccine should be given within 12 hours, and maternal blood should be drawn to determine status. If the mother’s surface antigen is positive, the child is given immune globulin as soon as possible, but no later than 1 week of age. For mothers with negative antigen status, the first dose of vaccine is given at 0–2 months, the second at 1–4 months, and the third at 6–18 months.
