Per the revised National Immunization Schedule (NIS) under India's UIP, the Measles-Rubella (MR) second dose is administered at:

• A 9 months (alongside MR first dose)
• B 24 months
• C 5–6 years at school entry
• D 15–18 months (with DPT booster-1) ✓

Explanation

Per the revised NIS, MR first dose is at 9–12 months and MR second dose is at 15–18 months, co-administered with DPT booster-1 and OPV booster-1. This schedule replaced the earlier 16–24 month window and aligns India more closely with the WHO two-dose measles elimination strategy. A minimum interval of 4 weeks must be maintained between the two MR doses.
