The purpose of this study is to evaluate the efficacy, immunogenicity and safety of the 9-valent human papillomavirus (9vHPV) vaccine in men 20 to 45 years of age. The primary hypothesis tested in this study is that administration of a 3-dose regimen of 9vHPV vaccine will reduce the incidence of HPV 16/18/31/33/45/52/58-related oral persistent infection (6 months or longer) compared with placebo.
