According to the current IAP Immunization Advisory Committee recommendations, the adolescent booster with acellular pertussis component (Tdap) should be administered at which age?
- A 5 years
- B 10 to 12 years ✓
- C 15 to 16 years
- D At any age after 18 years
Correct answer: B. 10 to 12 years
Explanation
The IAP schedule recommends a single dose of Tdap at 10 to 12 years, replacing the Td booster at this age, followed by Td every 10 years thereafter. The 5-year visit receives the second booster of DTwP or Td, so option A describes a different product and visit. The adolescent Tdap dose was introduced primarily to provide pertussis protection during the age when waning immunity drives transmission to young infants.
