Outcome Measures
Primary Outcomes (10)
Number of Participants Reporting Serious Adverse Experiences (SAEs) Through Month 18
Tolerability as assessed by the number of participants with clinical adverse experiences through Month 18. A serious adverse event is any adverse event that results in death, is life threatening, results in a persistent or significant disability/incapacity, results in hospitalization or prolongs an existing hospitalization, is a congenital anomaly/birth defect, is a cancer, is an overdose, or is considered an "other important medical event" based on medical judgment.
Up to Month 18
Number of Participants Reporting SAEs From Month 18 Through Month 37
Tolerability as assessed by the number of participants with clinical adverse experiences from Month 18 through Month 37
Month 18 to Month 37
Number of Participants Reporting Other (Non-serious) AEs Through Month 18
Tolerability as assessed by the number of participants with clinical adverse experiences through Month 18
Up to Month 18: Injection site AEs were collected from Days 1-5 and other non-serious AEs from Days 1-15 after any vaccination
Percentage of Participants Who Are Seropositive for HPV Types 6, 11, 16, and 18 at Month 72
A participant is considered seropositive for a given HPV type if he or she has a cLIA titer at or above the serostatus cutoff for that HPV type. Serostatus cutoffs are ≥ 20 mMU/mL for HPV 6 and 16, ≥ 16 mMU/mL for HPV 11, and ≥ 24 mMU/mL for HPV 18.
Month 72 (66 Months Post-dose 3 for the Original qHPV Vaccine Cohort and 36 months Post-dose 3 for the Extension Group)
Geometric Mean Titers (GMTs) for Anti-HPV 6, 11, 16, and 18 at Month 72
Month 72 (66 Months Post-dose 3 for the Original qHPV Vaccine Cohort and 36 months Post-dose 3 for the Extension Group)

Month 96 (90 Months Post-dose 3 for Original qHPV Vaccine Group and 60 Months Post-dose 3 for Extension Group)
Percentage of Participants Who Are Seropositive for HPV Types 6, 11, 16, and 18 at Month 96
A participant is considered seropositive for a given HPV type if he or she has a cLIA titer at or above the serostatus cutoff for that HPV type. Serostatus cutoffs are ≥ 20 mMU/mL for HPV 6 and 16, ≥ 16 mMU/mL for HPV 11, and ≥ 24 mMU/mL for HPV 18.

Month 126 (120 Months Post-dose 3 for Original qHPV Vaccine Cohort and 90 Months Post-dose 3 for Extension Group)
Percentage of Participants Who Are Seropositive for HPV Types 6, 11, 16, and 18 at Month 126
A participant is considered seropositive for a given HPV type if he or she has a cLIA titer at or above the serostatus cutoff for that HPV type. Serostatus cutoffs are ≥ 20 mMU/mL for HPV 6 and 16, ≥ 16 mMU/mL for HPV 11, and ≥ 24 mMU/mL for HPV 18.
Month 126 (120 Months Post-dose 3 for Original qHPV Vaccine Cohort and 90 Months Post-dose 3 for Extension Group)
Number of Participants Reporting SAEs Related to Study Vaccine or to a Study Procedure in the Long-term Follow-up
A serious adverse event is any adverse event that results in death, is life threatening, results in a persistent or significant disability/incapacity, results in hospitalization or prolongs an existing hospitalization, is a congenital anomaly/birth defect, is a cancer, is an overdose, or is considered an "other important medical event" based on medical judgment. SAEs considered by the investigator to be possibly, probably, or definitely related to study vaccine or a study procedure were reported.

Limitations and Caveats
The difference between the prior and final data is a minor change in the definition of the per-protocol immunogenicity population, which was applied down to the base study. Also, protocol violators were identified and excluded from the analysis.
