NIS Basics - India's Shield Plan
- Foundation of India's Universal Immunization Programme (UIP).
- Primary Goal: Prevent morbidity, mortality, and disability from Vaccine-Preventable Diseases (VPDs).
- Provides free, universal immunization to infants, children, and pregnant women.
- Dynamic schedule, regularly updated by GOI based on disease burden & vaccine availability.
- Crucial for improving child survival rates.
⭐ India's UIP, launched in 1985, was a significant expansion of the Earlier Programme on Immunization (EPI) from 1978.
Infant Schedule (Birth‑1 Yr) - Tiny Vax Titans
- Key Principle: Timely vaccination builds crucial early immunity against severe preventable diseases. Full schedule adherence is vital.
- Vaccines & Timeline:
| Age | Vaccine(s) | Notes |
|---|---|---|
| Birth | BCG, OPV-0, Hep B (Birth) | BCG: ID, LUA. OPV: Oral. HepB: IM, <24h. |
| 6 Weeks | OPV-1, Penta-1, Rota-1, PCV-1, fIPV-1 | Penta (DPT+HepB+Hib): IM. Rota: Oral. PCV: IM. fIPV: ID, RUA. |
| 10 Weeks | OPV-2, Penta-2, Rota-2 | Penta: IM. Rota: Oral. |
| 14 Weeks | OPV-3, Penta-3, Rota-3, PCV-2, fIPV-2 | Penta: IM. Rota: Oral. PCV: IM. fIPV: ID, RUA. |
| 9-12 Mo | MR-1, JE-1 (endemic), PCV Booster | MR: SC, RUA. JE: SC (endemic). PCV-B: IM. |
Child Schedule (1‑18 Yrs) - Booster & Beyond
- DPT 2nd Booster: 5-6 years.
- Reinforces Diphtheria, Pertussis, Tetanus immunity. Often a pre-school dose.
- Td Vaccine (Tetanus & adult Diphtheria):
- Given at 10 years & 16 years.
- Protects through adolescence. Adult 'd' means reduced diphtheria antigen.
- Catch-up: Vital for any missed primary vaccines (e.g., OPV, MMR, JE). Follow official catch-up guidelines.
- Key Missed Doses: Ensure MR/MMR (2nd dose) & JE (2nd dose) if not received at 16-24 months.
⭐ Td vaccine uses adult-type diphtheria toxoid (a lower 'd' antigen content) to minimize local reactions compared to the pediatric 'D' antigen in DPT. oka
Maternal Immunization - Womb‑to‑World Shield
- Protects mother & newborn (neonatal tetanus, diphtheria).
- Vaccine: Td (Tetanus & adult Diphtheria toxoid).
- Schedule for pregnant women:
- Td-1: Early in pregnancy.
- Td-2: 4 weeks after Td-1.
- Td-Booster: One dose if 2 Td doses in prior pregnancy <3 yrs ago.
⭐ All pregnant women receive at least two Td doses, or one booster if recently (within 3 years) fully vaccinated during a previous pregnancy.
NIS Updates & Special Points - Vax Facts Evolved
- Recent Changes: fIPV intro (2 doses: 6, 14 wks); RVV universalized (6, 10, 14 wks); PCV expansion (6w, 14w, 9m booster); MR for Measles; Td for TT (10, 16 yrs, pregnancy).
- Special Vaccines: JE in endemic districts (refer to state guidelines).
- Catch-up Principles: Vaccinate at earliest opportunity. Do not restart interrupted series. BCG till 1 yr; MR till 5 yrs (or campaign age).
⭐ fIPV: 0.1ml intradermal, right upper arm. Two doses at 6 & 14 weeks.
High‑Yield Points - ⚡ Biggest Takeaways
- BCG, OPV-0, Hep B-0 are crucial birth doses.
- Pentavalent vaccine combines DPT, Hib, and Hepatitis B.
- Measles-Rubella (MR) vaccine is given at 9-12 months and 16-24 months.
- Rotavirus vaccine (oral) is administered at 6, 10, and 14 weeks.
- Inactivated Polio Vaccine (IPV) is given as two fractional doses at 6 and 14 weeks.
- Td vaccine (Tetanus-diphtheria) replaces TT for pregnant women and older children/adolescents.
- Pneumococcal Conjugate Vaccine (PCV) schedule includes doses at 6, 14 weeks, and a booster at 9 months.
