A 2-year-old child from a Japanese encephalitis (JE) endemic district in India is brought for routine immunization. The child has never received JE vaccine. According to the current Universal Immunization Programme schedule, what is the correct JE vaccination regimen?

• A Single dose of live attenuated SA 14-14-2 vaccine at 9 months of age
• B Three doses of inactivated vaccine at 6 weeks, 10 weeks, and 14 weeks of age
• C Single dose of inactivated Vero cell-derived vaccine at 12 months of age
• D Two doses of live attenuated SA 14-14-2 vaccine at 9 months and 16 months of age ✓

Explanation

Under India's UIP, the live attenuated SA 14-14-2 JE vaccine is given in JE endemic districts as two subcutaneous doses: the first at 9 months (with MR first dose) and the second at 16 months (with MR second dose). This schedule has been in effect since the vaccine's introduction into the UIP in endemic states. Option A is incorrect because two doses are required. Option C describes an inactivated vaccine schedule, but India's UIP uses the live attenuated JE vaccine.
