Brief summary

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

Interventions

BIOLOGICALComparator: Quadrivalent Human Papillomavirus (HPV) vaccine

Quadrivalent HPV vaccine was provided by the SPONSOR in single-dose vials containing a volume of 0.75 mL. The vaccine was administered as a 0.5-mL intramuscular dose at Day 1, Month 2, and Month 6.

A single administration of 0.5 mL intramuscular injection in a limb opposite that of quadrivalent HPV injection at Day 1

a single administration of 0.5 mL intramuscular injection administered in a limb opposite that of quadrivalent HPV injection at Day 1

A single administration of 0.5 mL intramuscular injection in a limb opposite that of quadrivalent HPV injection at Month 1

BIOLOGICALComparator: Adacel™

A single administration of 0.5 mL intramuscular injection in a limb opposite that of quadrivalent HPV injection at Month 1
