## Universal Immunisation Programme Schedule at 6 Months **Key Point:** At 6 months of age, the UIP schedule mandates the second dose of DPT, IPV, Hepatitis B, and the second dose of PCV (Pneumococcal Conjugate Vaccine). ### UIP Immunisation Timeline | Age | Vaccines | | --- | --- | | Birth | BCG, OPV-0, Hepatitis B-1 | | 6 weeks (1.5 months) | DPT-1, IPV-1, Hepatitis B-1, PCV-1, Rotavirus-1 | | **6 months** | **DPT-2, IPV-2, Hepatitis B-2, PCV-2, Rotavirus-2** | | 9-10 months | OPV-1, IPV-3 | | 12 months | Measles/MR, DPT-3, Hepatitis B-3, PCV-3 | | 18 months | DPT-B1, OPV-B1, Hepatitis A-1 | **High-Yield:** The 6-month visit is a critical checkpoint in the UIP schedule. The second doses of all primary vaccines (except OPV which is given at 9-10 months) are administered at this age. **Clinical Pearl:** Rotavirus vaccine (if available in the state) is also given at 6 months as the second dose. The exact timing is flexible between 4–6 months, but 6 months is the standard checkpoint visit. **Mnemonic:** **"6M = DIP-2, HepB-2, PCV-2"** — At 6 months, give the 2nd dose of DPT (D), IPV (I), Hepatitis B (P for primary), and PCV (Pneumococcal). ### Why This Matters The UIP is designed to provide age-appropriate protection against vaccine-preventable diseases. At 6 months, the infant has received the first dose of most vaccines and requires the second dose to boost immunity and ensure adequate seroconversion. PCV-2 is particularly important for protection against invasive pneumococcal disease, which remains a leading cause of childhood morbidity in India.
