The birth dose of Hepatitis B vaccine is given when?

• A. At 2 months
• B. At birth
• C. At 6 weeks
• D. At 12 months

Answer: (B)

The birth dose is given at birth. Vaccinating newborns right away helps prevent Hepatitis B from being transmitted from mother to child and provides early protection, which is why the dose is given within 24 hours of birth (ideally as soon as feasible after delivery). The remaining doses in the Hepatitis B series are given later, typically at about 1–2 months and again around 6 months, not at birth. In certain situations, such as when the mother’s Hepatitis B status is positive or unknown, additional measures like HBIG may be used at birth, but the birth dose itself is the vaccination given immediately after birth.
