Outcome Measures

Primary Outcomes (1)

• Immunogenicity1: Anti-HPV 6, 11, 16, 18, 31, 33, 45, 52, and 58 type specific antibody levels at Months 7 in the population aged 9-26 years old receiving 3 doses of the nonavalent vaccine

  To determine whether the immune responses (antibodies to HPV-6, 11, 16, 18, 31, 33, 45, 52, and 58) at month 7 (one month after the final dose) in the population aged 9-17 years receiving 3 doses of the nonavalent vaccine are noninferior to those in women aged 18-26 years receiving 3 doses of vaccine.

  7 months after the first dose

Secondary Outcomes (6)

• Immunogenicity2: Anti-HPV 6, 11, 16, 18, 31, 33, 45, 52, and 58 type specific antibody levels at Months 7 in the population aged 9-14 years old receiving 2 doses of the nonavalent vaccine

  7 months after the first dose

• Immunogenicity3: Anti-HPV 6, 11, 16, 18, 31, 33, 45, 52, and 58 type specific antibody levels at months 18 and 30 in the population aged 9-14 and 15-17 years old receiving 2 doses or 3 doses of the nonavalent vaccine

  30 months after the first dose

• Safety1: Local and systematic adverse events/reactions occurred within 7 days after each vaccination.

  During the 7-day period following each vaccination

• Safety2: Adverse events/reactions occurred within 30 days after each vaccination.

  Within 30 days (Day 0-30) after any vaccination

• Safety3: Severe adverse events occurred throughout the study.

  Up to 8 month
