Time Perspective: Retrospective
Official Title: Post-Licensure Observational Study of the Safety of GARDASIL™ in Males

Further study details as provided by Merck Sharp & Dohme Corp.:

Primary Outcome Measures:
  • Incidence of health outcomes resulting in emergency room visits or hospitalizations in 60-day risk periods after each dose of GARDASIL™ compared to post-vaccination self-comparison periods [ Time Frame: Within 60 days after each dose ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Incidence of health outcomes resulting in emergency room visits or hospitalizations in the 60-day risk period following the first dose of GARDASIL™ compared to post-vaccination self-comparison periods [ Time Frame: Within 60 days after the first dose ] [ Designated as safety issue: Yes ]
  • Incidence of syncope, convulsive syncope, epilepsy, convulsions, head trauma, and allergic reactions on the day of vaccination [ Time Frame: Day of vaccination for each dose received (1 day for each dose, up to 3 total days) ] [ Designated as safety issue: Yes ]
  • Incidence of pre-specified new-onset conditions identified from the hospital, outpatient, and emergency room setting for 6 months after each dose of GARDASIL™ compared to the incidence of these conditions in an un-vaccinated population of males [ Time Frame: Within 6 months after each dose ] [ Designated as safety issue: Yes ]
