I now have everything from Park's textbook (2020 NIS). Let me compile this into a clean, memorable answer with tricks.
National Immunization Schedule (NIS) - Sites & Memory Tricks
Source: Park's Textbook of Preventive and Social Medicine, Table 43 (2020) + NHM official schedule
Full Schedule with Sites
| Vaccine | Route | Site |
|---|---|---|
| BCG | Intradermal | Left Upper Arm |
| Hep B (birth dose) | Intramuscular | Antero-lateral mid-thigh |
| OPV (0, 1, 2, 3, booster) | Oral | Oral (mouth) |
| RVV (Rotavirus) | Oral | Oral (mouth) |
| Pentavalent (1, 2, 3) | Intramuscular | Antero-lateral mid-thigh (Left) |
| fIPV (1 & 2) | Intradermal | Right Upper Arm |
| PCV (1, 2, booster) | Intramuscular | Antero-lateral mid-thigh |
| MR - 1st dose (9-12 months) | Subcutaneous | Right Upper Arm |
| JE - 1 (9-12 months) | Subcutaneous | Left Upper Arm |
| MR - 2nd dose (16-24 months) | Subcutaneous | Right Upper Arm |
| JE - 2 (16-24 months) | Subcutaneous | Left Upper Arm |
| DPT Booster-1 (16-24 months) | Intramuscular | Antero-lateral mid-thigh |
| DPT Booster-2 (5-6 years) | Intramuscular | Upper Arm |
| Td (10 yrs & 16 yrs) | Intramuscular | Upper Arm |
| Td (Pregnant women) | Intramuscular | Upper Arm |
Memory Tricks
TRICK 1 - "BOLT" for routes
BCG = iD (intradermal) OPV + Rota = Oral Left thigh for IM shots in infants (Penta, PCV, Hep B, DPT booster-1) Td / DPT (older) = Upper arm IM
TRICK 2 - "Left vs Right Arm" trick
Left arm = vaccines starting early or with "BCG feel"
- BCG - Left upper arm (intradermal)
- JE - Left upper arm (subcutaneous)
Right arm = Inactivated/killed injected vaccines given mid-schedule
- fIPV - Right upper arm (intradermal)
- MR - Right upper arm (subcutaneous)
Mnemonic: "BCG & JE go LEFT (B-J-L), MR & IPV go RIGHT (M-I-R)"
TRICK 3 - "THIGH = TINY BABY" rule
All IM injections in infants (< 2 years) go in the antero-lateral mid-thigh (safest IM site in babies due to large muscle mass there):
- Hep B (birth)
- Pentavalent (6, 10, 14 weeks)
- PCV (6, 14 weeks + booster)
- DPT Booster-1 (16-24 months)
Mnemonic: "Tiny babies get thigh shots - HPPD (Hep B, Penta, PCV, DPT booster-1)"
TRICK 4 - "ORAL = Pour it down"
OPV (2 drops) and Rotavirus (3 drops) are both oral - no injection needed.
Remember: "PouR - Polio (2 drops) and Rota (3 drops)"
TRICK 5 - ROUTE Summary Table
| Route | Vaccines |
|---|---|
| Oral | OPV, Rotavirus |
| Intradermal (ID) | BCG (Left arm), fIPV (Right arm) |
| Subcutaneous (SC) | MR (Right arm), JE (Left arm) |
| Intramuscular (IM) | Everything else: Hep B, Penta, PCV, DPT, Td - all in thigh (infants) or upper arm (older) |
Quick Revision Rhyme
"BCG goes LEFT ID, IPV goes RIGHT ID, MR Right SC, JE Left SC, Babies get thighs for their IM shots, OPV and Rota - just drops in the mouth!"
This covers the complete NIS as per Park's Preventive Medicine (2020) and the NHM official schedule. The key principle to anchor everything: only 2 routes in the arm (ID = BCG left, fIPV right; SC = MR right, JE left), and all IM in infants go to the thigh.
