In the IAP immunisation schedule, the Rotavirus vaccine (RV1 — Rotarix) is given as 2 doses. What is the maximum age for the FIRST dose, and the maximum age for the LAST dose?
- A First dose by 15 weeks; last dose by 32 weeks
- B First dose by 20 weeks; last dose by 24 weeks
- C First dose by 12 weeks; last dose by 24 weeks ✓
- D No age restriction applies to RV1
Correct answer: C. First dose by 12 weeks; last dose by 24 weeks
Explanation
RV1 (Rotarix, 2-dose schedule) has strict age restrictions per WHO and IAP: the first dose must not be given after 15 weeks (maximum 14 weeks 6 days; IAP/WHO recommend starting at 6 weeks); the second dose must not be given after 24 weeks (maximum 8 months) to minimise a theoretically increased risk of intussusception when RV vaccination is given to older infants. RV5 (RotaTeq, 3-dose schedule) has a first dose age maximum of 12 weeks and last dose by 32 weeks. Beginning early (6–10 weeks) and completing before 24 weeks is optimal.
