Published in Newborn Vaccination 1 min read

The first vaccine most newborns receive is the Hepatitis B vaccine.

Importance of Early Vaccination

According to HealthyChildren.org, the Hepatitis B vaccine is typically administered within 24 hours of birth. This early vaccination is crucial because:

  • It protects newborns from contracting Hepatitis B, a serious liver infection.
  • Babies are especially vulnerable to complications from Hepatitis B, which can become a chronic condition if contracted in infancy.
  • The vaccine's effectiveness is higher when given shortly after birth.

Hepatitis B Vaccine Schedule

The Hepatitis B vaccine is administered in a series of doses:

  1. First Dose: Given within 24 hours of birth.
  2. Second Dose: Administered when the baby is between 1 to 2 months old.
  3. Third Dose: Given between 6 to 18 months of age.


Vaccine When is it Given?
Hepatitis B Within 24 hours of birth
Hepatitis B 1-2 months of age
Hepatitis B 6-18 months of age


This schedule ensures that the baby develops full immunity against the Hepatitis B virus.
