A newborn infant receives the first dose of hepatitis B vaccine within 12 hours of birth. The nurse instructs the parent regarding the immunization schedule for this vaccine and should tell the parent that the second vaccine is administered at which time periods?
ExplanationThe vaccination schedule for an infant whose mother tests negative for hepatitis B consists of a series of 3 immunizations given at 0 months (birth), 1 to 2 months of age, and then 6 months after the initial dose. An infant whose mother tests positive receives hepatitis B immune globulin along with the first dose of the hepatitis vaccine within 12 hours of birth.
