Regarding the IAP immunisation schedule for rotavirus vaccine, all of the following statements are true EXCEPT:

Explanation

## Rotavirus Vaccine – IAP Schedule & Administration **Key Point:** The IAP immunisation schedule specifies that the first dose of rotavirus vaccine must be administered **before 15 weeks of age** (not 12 weeks), to balance intussusception risk with optimal immunogenicity. ### Rotavirus Vaccine Characteristics (Correct Statements) | Feature | Details | |---------|---------| | Type | Live attenuated oral vaccine (Rotavac / RotaTeq / Rotarix) | | First dose window | Must be given **before 15 weeks** of age (ideally at 6 weeks) | | Primary series | 2 or 3 doses depending on brand (6, 10, 14 weeks for 3-dose schedules) | | Route | Oral | | Efficacy | ~90% protection against severe rotavirus gastroenteritis | **High-Yield (IAP 2023):** The IAP schedule states the first dose of rotavirus vaccine should be given at **6 weeks** and the series must be initiated **before 15 weeks of age** (upper age limit for first dose). Option B states "before 12 weeks," which is **incorrect** — this is the FALSE statement and hence the correct answer for this EXCEPT question. ### Why the Age Limit Matters The age restriction exists because intussusception risk is higher when the vaccine is given to older infants (>15 weeks). The WHO and IAP both set the upper limit for the first dose at **15 weeks (104 days)**, not 12 weeks. Giving the first dose before 6 weeks is also not recommended. ### Co-administration with Other Live Vaccines **Clinical Pearl:** Rotavirus vaccine (oral live attenuated) **CAN be co-administered with other live vaccines** (including OPV, BCG) on the same day, as per both IAP and WHO guidelines. This is because oral rotavirus vaccine does not interfere with parenteral live vaccines. Inactivated vaccines can also be co-administered freely. Option D is therefore a **true** statement and is NOT the exception. ### IAP Rotavirus Schedule Summary | Dose | Age | |------|-----| | Dose 1 | 6 weeks (must start before 15 weeks) | | Dose 2 | 10 weeks | | Dose 3 | 14 weeks (for 3-dose schedules) | **Mnemonic: RVV 6-10-14** — Rotavirus Vaccine at **6**, **10**, **14** weeks **Reference:** IAP Immunisation Timetable 2023; WHO position paper on Rotavirus vaccines (2013, updated 2023); Nelson Textbook of Pediatrics, 21st edition. **Tip:** The key distinguishing fact: first dose upper age limit = **15 weeks** per IAP/WHO, NOT 12 weeks. Option B is the false statement.
