Primary outcomePrimary: Geometric Mean Titers (GMTs) of the Antibody Response to Each of the Human Papillomavirus (HPV) Types Contained in V503 — 2198.7; 2260.7; 1495.0; 1547.2 milli Merck Units/mL — p=<0.001
Summary
This study will evaluate the tolerability and immunogenicity of administration of the first dose of V503 at the same time as Menactra™ and Adacel™ versus administration of V503 one month prior to administration of Menactra™ and Adacel™.
