Correct answer is: Pertussis
Explanation:
It was licensed in the United States for use in adults and adolescents on June 10, 2005. The lower-case "d" and "p" indicated smaller concentrations of diphtheria toxoids and pertussis antigens, and "a" in "ap" indicates that the pertussis toxoids are acellular. Two Tdap vaccines are available in the US.
