Rotavirus vaccine (RVV) was included in India's UIP. Which of the following CORRECTLY describes the administration schedule for Rotarix (RV1) as given under India's programme?
- A 3 oral doses at 6, 10, 14 weeks
- B 2 oral doses at 6 and 10 weeks ✓
- C 2 oral doses at 6 and 14 weeks
- D 3 oral doses at 6, 10, 14 weeks and a booster at 9 months
Correct answer: B. 2 oral doses at 6 and 10 weeks
Explanation
India introduced Rotarix (RV1 — 2-dose oral vaccine) in its UIP with doses at 6 and 10 weeks, co-administered with OPV and DPT. The first dose must be given before 15 weeks of age (WHO recommends completion before 24 weeks for RV1). RotaTeq (RV5), used in the USA, requires 3 doses. India's UIP uses Rotarix (2 doses) — not a 3-dose schedule. The doses are given at 6 and 10 weeks (not 6 and 14 weeks — option C), fitting within the DPT co-administration schedule.
