When is the birth dose of the Hepatitis B vaccine given?

Explanation:
Giving the Hepatitis B birth dose at birth, ideally within 24 hours of delivery, is done to prevent mother-to-child transmission right from the start. Vaccinating this early primes the infant’s immune system before exposure to the virus during birth, providing protection as soon as possible. The subsequent doses are scheduled later (usually at about 1–2 months and again around 6–18 months) to complete protection. Therefore, doses given at 2 months, 6 weeks, or 12 months do not fulfill the purpose of the birth dose.
