What was measured

Combined Incidence of HPV Type 31/33/45/52/58-related persistent infection as determined by clinical/pathologic criteria and positive Polymerase Chain Reaction (PCR) assay for virus subtype. Persistent infection was defined as infection detected in samples from \>=2 consecutive visits 6 months (+/-1 month visit window) or longer apart. Incidence was defined as the number of cases of persistent infection per 10,000 person-years of follow-up in a treatment arm.

Analysis population: The Per-protocol Efficacy population included all participants who received all 3 vaccinations of mid-dose V503 or Gardasil within acceptable day ranges, were seronegative at Day 1 and PCR negative at Day 1 through Day 7 to the relevant HPV types, and had at least 1 follow-up visit following Month 7.

Groups in this outcome

Mid-dose V503

V503 (9-Valent HPV Vaccine) mid-dose 0.5 mL injection in a 3-dose regimen in the base study. A subset of participants (Cohort 1) received a fourth V503 mid-dose vaccination in the extension study.

Gardasil

Gardasil (4-Valent HPV Vaccine) 0.5 mL injection in a 3-dose regimen in the base study. Participants (Cohort 2) were offered the V503 mid-dose 3-dose regimen in the extension study.
