Case # 1
You are rotating in the newborn nursery. Your next admission is a term newborn born at 3.5 kg, and all
maternal labs are negative. The infant's exam is normal.
1. What vaccine(s) should she receive and why?
In accordance with the Center for Disease Control and Prevention (CDC), it is
recommended that the newborn infant receive the first of three Hepatitis B doses. The first dose
should be administered within 24 hours of birth for infants greater than or equal to 2,000 grams
that are deemed stable (CDC, 2020). Hep B vaccines are a means of preventing infections that
are secondary to the hep B virus (Pinto et al., 2017). The goal of HBV vaccinations is to prevent
chronic infections and decrease the risk of transmission in preadolescent and adulthood. (Pinto
et al., 2017).
2. What would you do if the mother tested positive for Hepatitis B?
If the mother tests positive for Hep B, the infant should receive the first Hep B vaccine
as well as the Hep B immune globulin (HBIG) within the first 12 hours of birth (CDC, 2020). The
vaccines can be administered regardless of the infant’s weight at birth. However, if the infant is
less than 2,000 grams, three additional hep B doses should be administered beginning at 1
month of age (CDC, 2020). Between 9 and 12 months of age, the provider should test the child
for HBsAg and anti-HBs.
3. What would you do if the mother's Hepatitis B status was unknown?
If the status of the mother is unknown, the infant should receive the Hep B vaccine
within 12 hours of birth regardless of weight (CDC, 2020). If the infant is less than 2,000 grams,
he/she should receive the first Hep B vaccine as well as the HBIG within the first 12 hours after
birth. Beginning at one month of age, the infant should receive the Hep B series with the three
