Under the Indian National Immunization Schedule (NIS), which vaccine is administered to a child at 16-24 months of age as a booster?
- A DPT first booster
- B DPT second booster ✓
- C OPV second booster
- D MR second dose
Correct answer: B. DPT second booster
Explanation
Under India's NIS, the DPT first booster is given at 16-24 months. The OPV booster is also given at this age, but option C says 'second booster' which is incorrect terminology. MR second dose is given at 15-18 months. The DPT second booster (as DPT or Td) is given at 5-6 years, not 16-24 months.
