Q

What do the capital and lower-case letters mean?

A

Upper-case letters denote full-strength doses of diphtheria (D) and tetanus (T) toxoids and pertussis (P) vaccine. The “a” in DTaP and Tdap stands for “acellular,” meaning that the pertussis component contains only a part of the pertussis organism

– Lower-case “d” and “p” denote reduced doses of diphtheria and pertussis used in the adolescent/adult-formulations.
