- Percentage of Participants Who Experience an Injection-site Adverse Event (AE) - Base Study [ Time Frame: up to 5 days after any vaccination - Base Study ]An AE is defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the study vaccine, whether or not considered related to the use of the vaccine. Any worsening of a preexisting condition which is temporally associated with the use of the study vaccine is also an AE. The percentage of participants who reported an AE that was associated with the injection site such as redness, swelling, and pain/tenderness/soreness was summarized.
- Percentage of Participants With Body Temperature ≥100.0°F (≥37.8ºC) - Base Study [ Time Frame: up to 5 days after any vaccination - Base Study ]Participants collected their oral body temperature in the evening of their vaccination day and at the same time each day thereafter for 4 days. The maximum body temperature obtained within 5 days of any of the 3 vaccinations was recorded.
- Percentage of Participants Who Experience a Systemic AE - Base Study [ Time Frame: up to 14 days after any vaccination - Base Study ]An AE is defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the study vaccine, whether or not considered related to the use of the vaccine. Any worsening of a preexisting condition which is temporally associated with the use of the study vaccine is also an AE. Systemic AEs were those not categorized as injection-site AEs.
- Percentage of Participants Who Experience a Serious Adverse Event (SAE) Within 15 Days of Any Vaccination - Base Study [ Time Frame: up to 14 days after any vaccination - Base Study ]An SAE is one that results in death, disability/incapacity, or hospitalization or is life threatening, a congenital anomaly or birth defect, cancer, an overdose, or otherwise jeopardizes the participant and may require medical intervention.
- Percentage of Participants Who Experience a Vaccine-related SAE Any Time During Study- Base Study [ Time Frame: Up to 7 months - Base Study ]An SAE is one that results in death, disability/incapacity, or hospitalization or is life threatening, a congenital anomaly or birth defect, cancer, an overdose, or otherwise jeopardizes the participant and may require medical intervention. An SAE that is judged by the Investigator to be "definitely related," "probably related," or "possibly related" is defined as a vaccine-related SAE.
- Percentage of Participants Who Experience a Severe Injection-site AE - Base Study [ Time Frame: up to 5 days after any vaccination - Base Study ]An AE is defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the study vaccine, whether or not considered related to the use of the vaccine. Any worsening of a preexisting condition which is temporally associated with the use of the study vaccine is also an AE. Participants were instructed to estimate the severity of AEs such as pain at injection site as mild (awareness of symptom, but easily tolerated), moderate (discomfort enough to cause interference with usual activities), or severe (incapacitating with inability to work or do usual activity). Additionally, participants were instructed to measure any swelling and/or erythema at its greatest width. Swelling or erythema with diameter >2 inches (>5 cm) was recorded as severe. All AEs associated with the injection site and reported as severe were summarized.
- Percentage of Participants Who Seroconvert to Each of the HPV Types Contained in the Vaccine - Base Study [ Time Frame: 4 weeks post-vaccination 3 (Month 7; End of Base Study) ]Serum antibody titers for HPV virus-like particles (VLPs), Types 6, 11, 16, 18, 31, 33, 45, 52 and 58 were determined 4 weeks post-vaccination 3 using competitive luminex immunoassay (cLIA). The serostatus cutoffs (milli Merck U/mL) for HPV types were as follows: HPV Type 6: ≥30, HPV Type 11: ≥16; HPV Type 16: ≥20, HPV Type 18: ≥24, HPV Type 31: ≥10, HPV Type 33: ≥8, HPV Type 45: ≥8, HPV Type 52: ≥8, and HPV Type 58: ≥8.
- Percentage of Participants Who Experience an SAE- Extension Study [ Time Frame: up to Month 7 - Extension Study ]An SAE is one that results in death, disability/incapacity, or hospitalization or is life threatening, a congenital anomaly or birth defect, cancer, an overdose, or otherwise jeopardizes the participant and may require medical intervention.
