📋 NATIONAL IMMUNIZATION SCHEDULE TABLE

👩‍🍼 A. FOR PREGNANT WOMEN

📝 Exam Note: Td has REPLACED TT (Tetanus Toxoid) in NIS. Td = Tetanus + adult Diphtheria (low dose)

---

👶 B. FOR INFANTS (Birth to 1 year)

---

🧒 C. FOR CHILDREN (16 months onwards)

---

🔷 PENTAVALENT VACCINE (Very Important!)

Pentavalent = DPT + Hepatitis B + Hib (Haemophilus influenzae type b)
            ↓
   Given at 6, 10, 14 weeks
   
⚠️ Once Pentavalent is used at 6-10-14 weeks,
   separate DPT, Hep B, and Hib are NOT given

---

🔷 IAP SCHEDULE vs UIP/NIS SCHEDULE

📝 Exam Note: IAP includes more vaccines because UIP has financial constraints

---

💉 VITAMIN A SUPPLEMENTATION SCHEDULE (IMPORTANT!)

Age 9 months   → 1 lakh IU (1,00,000 IU) given with MR vaccine
Age 16 months  → 2 lakh IU (2,00,000 IU) with DPT Booster
Then EVERY 6 MONTHS until 5 years → 2 lakh IU each time
                        (Total = 9 doses)

🧠 MNEMONICS

Routes of Administration:

"ID BRother, IM BIG, SC MR, Oral POOR"
  ID  = BCG, fIPV
  IM  = Hep B, Pentavalent, PCV, DPT, Td
  SC  = MR (Measles-Rubella), Varicella
  Oral= OPV, Rotavirus, Vitamin A

Vaccines given at BIRTH (mnemonic: "BHO"):

B = BCG
H = Hepatitis B (within 24 hours!)
O = OPV (within 15 days)

Vaccines at 6-10-14 weeks (mnemonic: "PROP"):

P = Pentavalent (DPT + Hep B + Hib)
R = Rotavirus
O = OPV
P = (f)IPV at 6 and 14 weeks only (not 10!)
(+PCV at 6 and 14 weeks only)

---

⚠️ IMPORTANT EXAM POINTS

---

🔷 COLD CHAIN REQUIREMENTS

Vaccine Temperature Storage:
├── -15°C to -25°C: OPV, Varicella
├── +2°C to +8°C: BCG, DPT, Hep B, Pentavalent, PCV, Rotavirus, fIPV, MR, Td
└── ⚠️ NEVER FREEZE: Hep B, Pentavalent, PCV, DPT, Td

---
