This phase 3 study will evaluate the immunogenicity and safety of 9-valent HPV recombinant vaccine in Chinese females aged 9 to 45 years
This study (protocol 9-HPV-3003) is an immunogenicity and safety study in the subjects (9-19 years of age) who received the 9-valent HPV recombinant vaccine compared with the subjects (20-45 years of age). In this study, we will assess whether the immunogenicity of the 9-valent HPV vaccine given 3-dose schedule in the subjects (9-19 years of age) in noninferior to that in the subjects (20-45 years of age) receiving 3 doses, while assessing the safety of this vaccine.

RECRUITINGThe primary immunogenicity objective
The primary outcome measure for assessing vaccine immunogenicity, among subjects aged between 9 and 45, is the results of seroconversion rate of neutralizing antibodies after immunization in pre-immune negative subjects from 30 days after the last dose (3 doses schedule, Month 7) to HPV 6, 11, 16, 18, 31, 33, 45, 52 , and 58.
Time frame: 30 days after the last dose(3 doses schedule)
Number of patients with postive antibodies after the whole schedule vaccination from the former negative subjects
The secondary outcome measure for assessing vaccine immunogenicity, among subjects aged between 9 and 45, is the geometric mean titer (GMT) from 30 days after the last dose (3 doses schedule, Month 7) to HPV 6, 11, 16, 18, 31, 33, 45, 52 , and 58.
Time frame: 30 days after the last dose(3 doses schedule)
Rate of seroconversion among the patient aged 9-26 after the whole schedule vaccination
To assess vaccine immunogenicity among the subjects aged between 9 and 26, is the seroconversion rate of neutralizing antibodies and the GMT from 30 days after the last dose (3 doses schedule, Month 7) to HPV 6, 11, 16, 18, 31, 33, 45, 52 , and 58.
Time frame: 30 days after the last dose(3 doses schedule)
GMT and seropositive rate of HPV in the 9-19 age group after 60-month follow-up
After receiving all 3 doses vaccinations, the subjects aged 9 to 19 years will be followed for 60 month (Month 12/24/36/48/60) after first vaccination to assess the GMT and seropositive rate (4-fold-increase) to HPV 6, 11, 16, 18, 31, 33, 45, 52, and 58.
Time frame: Day 1 to 60 months post vaccination 3
