Which statement accurately describes the DTaP vaccination schedule regarding route and booster?

• A. Oral; Booster: Tdap
• B. Given IM; Booster: Tdap
• C. Subcutaneous; Booster: Td
• D. Intramuscular; Booster: Tdap

Answer: (D)

DTaP is given as an intramuscular injection, not by mouth or under the skin. For boosters, the appropriate follow-up is a Tdap shot (tetanus, diphtheria, and acellular pertussis), not Td, because Tdap includes pertussis protection. In practice, children receive the DTaP primary series in infancy and early childhood, with a Tdap booster recommended later (typically around 11–12 years) to maintain protection, and Td or Tdap every 10 years afterward as appropriate. This combination—intramuscular administration and a Tdap booster—best matches the vaccination schedule described.
