Incorrect Wording and Data: In the Original Contribution entitled “Combined Tetanus, Diphtheria, and 5-Component Pertussis Vaccine for Use in Adolescents and Adults” published in the June 22/29, 2005, issue of JAMA (2005;293:3003-3011), incorrect wording appeared at the end of the Results section. On page 3009, lines 15-16 of the fourth paragraph, “ . . . the complaint resolved within 1 day” should read “the patient was hospitalized for 1 day and the complaint subsequently resolved without sequelae.” In addition, in Table 4, for the entry “Axillary node swelling,” in column 2 (Tdap Adolescents) 676 should be 67.
