Comvax is approved for children between the ages of 6 weeks and 15 months. It should be noted that the Centers for Disease Control (CDC) recommends that all infants receive a hepatitis B vaccine shortly after birth, preferably while still in the hospital -- this is especially important for infants born to mothers with hepatitis B.
Comvax cannot be used for this early vaccination. However, the full recommended series (all three doses) can still be given at the usual times, even if an infant gets a hepatitis B vaccine at birth (this means the infant will receive one more hepatitis B vaccine dose than necessary).
