## IAP Immunisation Schedule — First Year of Life ### Vaccines Given in First Year (0–12 months) **Key Point:** The IAP schedule aligns closely with the National Immunisation Schedule (NIS) but may have some additions or variations. The critical distinction is the **timing** of each vaccine. ### Hepatitis B Vaccine **High-Yield:** Hepatitis B vaccine is given as: - Birth dose (within 24 hours) - 6 weeks (or 6 months) - 10 weeks (or 10 months) - 14 weeks (or 14 months) All doses are completed within the first year of life. ### Measles Vaccine **Key Point:** The first dose of measles (or MMR) is administered at **9 months of age** under both NIS and IAP schedules. This is within the first year of life. ### DPT (Diphtheria, Pertussis, Tetanus) Vaccine **Clinical Pearl:** DPT is administered at 6, 10, and 14 weeks of age. All three primary doses are completed within the first year of life. ### Varicella Vaccine — The Exception **Warning:** Varicella vaccine is administered at **12–15 months of age**, which is **after the first year of life** (i.e., after 12 months). Although the first dose may be given at the tail end of the 12-month window, the standard recommendation is 12–15 months, placing it in the **second year of life**, not the first year. **Clinical Pearl:** Varicella is not part of the mandatory NIS but is recommended by IAP as an optional vaccine. The first dose is given at 12–15 months, and a second dose at 18–24 months. | Vaccine | Age (Weeks/Months) | Within First Year? | |---------|-------------------|-------------------| | Hepatitis B | Birth, 6, 10, 14 weeks | ✓ Yes | | DPT | 6, 10, 14 weeks | ✓ Yes | | Measles/MMR | 9 months | ✓ Yes | | Varicella | 12–15 months | ✗ No (Second year) | | BCG | Birth | ✓ Yes | | Rotavirus | 6, 10, 14 weeks | ✓ Yes | | PCV | 6, 10, 14 weeks | ✓ Yes | **Mnemonic:** **"First Year: HBV, DPT, Measles at 9 mo. Varicella starts at 12 mo — that's Year 2."**
