Japanese encephalitis vaccination under India's National Immunization Schedule is offered in endemic districts. Which of the following correctly describes it?
- A Killed mouse brain vaccine, two doses at 6 and 7 months
- B Live attenuated SA 14-14-2 vaccine, single dose at 9 to 12 months of age ✓
- C Live attenuated vaccine, two doses at birth and 6 weeks
- D Recombinant chimeric vaccine, single dose at 16 to 24 months only
Correct answer: B. Live attenuated SA 14-14-2 vaccine, single dose at 9 to 12 months of age
Explanation
India uses the live attenuated SA 14-14-2 (live, attenuated, derived from the SA 14 strain) JE vaccine given as a single dose at 9 to 12 months together with the first dose of MR vaccine, in endemic states such as Uttar Pradesh, Assam and Bihar. Campaign catch-up rounds target children up to 15 years. The killed mouse brain vaccine is obsolete, and the chimeric vaccine is not part of the Indian programme.
