Neonatal Vaccines

Newborns should receive their first dose of hepatitis B vaccine within the first 24 hours of birth. Newborns who for a medical or other reason did not get the vaccine at birth should get their first dose as soon as possible, and complete all 3 doses at the recommended intervals.  The AAP recommends that all medically stable preterm babies with a minimum birth weight of 2000 grams should be treated like full-term babies and receive the first dose of the hepatitis B immunization according to the recommended childhood immunization schedule. If birth weight is less than 2000 g, the AAP recommends administering the hepatitis B vaccine at one month of age or at the time of discharge from the hospital – whichever comes first.​
