## National Immunisation Schedule — Hepatitis B Vaccination ### Correct Statements **Key Point:** The NIS of India follows a well-defined schedule for all vaccine administration. | Vaccine | Schedule | Doses | | --- | --- | --- | | BCG | Birth or within first year | Single dose | | OPV/IPV (Polio) | 6, 10, 14 weeks + booster at 18 months | 4 doses | | MR (Measles-Rubella) | 9 months + booster at 18 months | 2 doses | | Hepatitis B | Birth, 6 weeks, 10 weeks, 14 weeks | **3 primary doses** | ### The Error **High-Yield:** Hepatitis B vaccine under the NIS consists of **3 primary doses** (at birth, 6 weeks, and 14 weeks), not 4 doses. The 10-week dose is for other vaccines (pentavalent, PCV, rotavirus), not hepatitis B. **Clinical Pearl:** The birth dose of Hepatitis B is critical for prevention of vertical transmission and should be given within 24 hours of birth, ideally before the baby leaves the delivery room. ### Correct Hepatitis B Schedule 1. **Birth dose** — within 24 hours 2. **6 weeks** — as part of primary series 3. **14 weeks** — final primary dose No dose is given at 10 weeks for Hepatitis B alone (this is when pentavalent, PCV, and rotavirus are administered).
