Within 7 days after vaccine Dose 1 (administered at Day 1)

Assessed solicited administration site events included pain, redness and swelling at injection site. Grade 3 pain = significant pain at rest, which prevented normal everyday activities. Grade 3 redness/swelling = redness/swelling with a surface diameter greater than (\>) 50 millimeters (mm).

Number of Participants Reporting Grade 3 Solicited Administration Site Events After Vaccine Dose 2
Within 7 days after vaccine Dose 2 (administered at Month 2)

Assessed solicited administration site events included pain, redness and swelling at injection site. Grade 3 pain = significant pain at rest, which prevented normal everyday activities. Grade 3 redness/swelling = redness/swelling with a surface diameter \>50 mm.

Assessed solicited systemic events included fever, headache, myalgia, arthralgia and fatigue. Grade 3 fever = body temperature \>39.0°C or 102.2°F. The preferred location for measuring temperature was the axilla. Grade 3 headache, myalgia, arthralgia and fatigue = symptoms that prevented normal, every day activity.

Number of Participants Reporting Grade 3 Unsolicited Adverse Events (AEs) After Vaccine Dose 1
Within 28 days after vaccine Dose 1 (administered at Day 1)

An unsolicited AE is defined as an AE that was not included in the list of solicited events using an eDiary and that was spontaneously communicated by a participant/participant's parent(s)/legally acceptable representative(s) \[LAR(s)\] who has signed the informed consent. Also, any 'solicited' symptom with onset outside the specified period of follow-up for solicited symptoms was reported as an unsolicited AE. Grade 3 unsolicited AEs = an AE which prevented normal, everyday activities.

Number of Participants Reporting Grade 3 Unsolicited AEs After Vaccine Dose 2
Within 28 days after vaccine Dose 2 (administered at Month 2)

An unsolicited AE is defined as an AE that was not included in the list of solicited events using an eDiary and that was spontaneously communicated by a participant/participant's parent(s)/LAR(s) who has signed the informed consent. Also, any 'solicited' symptom with onset outside the specified period of follow-up for solicited symptoms was reported as an unsolicited AE. Grade 3 unsolicited AEs = an AE which prevented normal, everyday activities.

Number of Participants Reporting Grade 3 Unsolicited AEs After Vaccine Dose 3
Within 28 days after vaccine Dose 3 (administered at Month 6)

An unsolicited AE is defined as an AE that was not included in the list of solicited events using an eDiary and that was spontaneously communicated by a participant/ participant's parent(s)/LAR(s) who has signed the informed consent. Also, any 'solicited' symptom with onset outside the specified period of follow-up for solicited symptoms was reported as an unsolicited AE. Grade 3 unsolicited AEs = an AE which prevented normal, everyday activities.

Number of Participants Reporting Serious Adverse Events (SAEs)
From first vaccination (Day 1) to study end (Month 12)

An SAE is defined as any untoward medical occurrence that resulted in death, was life-threatening, required inpatient hospitalization or prolongation of existing hospitalization, resulted in disability/incapacity, was a congenital anomaly/birth defect in the offspring of a study participant, or resulted in abnormal pregnancy outcomes, or in other situations that were considered serious per medical or scientific judgment.

Number of Participants in Step 1 Subset With Clinically Relevant Biochemical Abnormalities
At Day 7

As pre-specified in the protocol, the assessed biochemical parameters were blood urea nitrogen (BUN), alanine aminotransferase (ALT) and aspartate aminotransferase (AST). Assessment of intensity: Grading of the biochemical parameters was based on the institutional normal reference ranges and derived from the standard Food and Drug Administration (FDA) Toxicity Grading Scale. Changes compared to normal reference ranges were graded as follows: Grade 0 = a non-missing parameter value for which grade could not be derived according to the grading scale and does not belong to Grade 1-4; Grade 1 = Mild; Grade 2 = Moderate; Grade 3 = Severe; Grade 4 = Potentially Life-Threatening. Unknown = parameter value missing for the specified parameter.

Number of Participants in Step 1 Subset With Clinically Relevant Hematological Abnormalities
At Day 7

As pre-specified in the protocol, the assessed hematological parameters were hemoglobin, white blood cells (WBC) increase, WBC decrease, lymphocyte decrease, neutrophils decrease, eosinophils, and platelets decrease. Assessment of intensity: Grading of the biochemical parameters was based on the institutional normal reference ranges and derived from the standard FDA Toxicity Grading Scale. Changes compared to normal reference ranges were graded as follows: Grade 0 = a non-missing parameter value for which grade could not be derived according to the grading scale and does not belong to Grade 1-4; Grade 1 = Mild; Grade 2 = Moderate; Grade 3 = Severe; Grade 4 = Potentially Life-Threatening; Unknown = parameter value missing for the specified parameter.

Number of Participants in Step 1 Subset With Clinically Relevant Abnormalities in Hemoglobin Change From Baseline Levels
At Day 7 compared to baseline (Day 1)

The number of participants with clinically relevant abnormalities in hemoglobin change from baseline levels is reported. Assessment of intensity: Grading of the biochemical parameters was based on the institutional normal reference ranges and derived from the standard FDA Toxicity Grading Scale. Changes compared to normal reference ranges were graded as follows: Grade 0 = a non-missing parameter value for which grade could not be derived according to the grading scale and does not belong to Grade 1-4; Grade 1 = Mild; Grade 2 = Moderate; Grade 3 = Severe; Grade 4 = Potentially Life-Threatening; Unknown = parameter value missing for the specified parameter. Change from baseline = the difference between a participant's baseline (pre-intervention) parameter values and their follow-up (post-intervention) parameter values.

Anti-HPV Immunoglobulin G (IgG) Antibody Concentrations
At Month 7 (one month after vaccine Dose 3 administration)

Anti-HPV IgG antibody concentrations were determined by electrochemiluminescence (ECL) assay and expressed as geometric mean concentrations (GMCs) in arbitrary units per milliliter (AU/mL). The assessed antigens were: HPV 6, HPV 11, HPV 16, HPV 18, HPV 31, HPV 33, HPV 45, HPV 52 and HPV 58 type antigens.
