Concomitant Use of Gardasil (V501, Human Papillomavirus [Types 6, 11, 16, 18] Recombinant Vaccine) With Combined Diptheria, Tetanus, Pertussis and Poliomyelitis Vaccine in Adolescents (V501-024)(COMPLETED)

September 27, 2016 updated by: Merck Sharp & Dohme LLC

An Open-Label, Randomized, Multicenter Study of the Safety, Tolerability, and Immunogenicity of Gardasil (V501) Given Concomitantly With REPEVAX™ in Healthy Adolescents 11-17 Years of Age

Data from this study are expected to demonstrate that Gardasil (V501, Human Papillomavirus [Types 6, 11, 16, 18] Recombinant Vaccine), when administered concomitantly with a combined diphtheria, tetanus, pertussis, and poliomyelitis vaccine in adolescents remains immunogenic and well-tolerated and it does not impair the immunogenicity of the concomitant vaccines.
