A 6-year-old child is due for vaccination under the Indian National Immunization Schedule. The child has received all previous doses correctly. Which vaccine is given at this age?
- A DPT booster
- B OPV booster
- C Td booster ✓
- D MR second dose
Correct answer: C. Td booster
Explanation
Under the Indian NIS, at 5-6 years, Td (Tetanus and adult diphtheria) vaccine is given as a booster. The switch from DPT to Td occurs because whole-cell or acellular pertussis vaccine is not recommended beyond 6 years of age due to increased reactogenicity. DPT booster is given at 16-24 months, OPV booster at 16-24 months, and MR second dose at 15-18 months.
