简要总结
The purpose of this study is to evaluate the immunogenicity and safety of three consecutive lots of bivalent HPV (Type 16,18) vaccine (Pichia pastoris) in healthy female subjects aged 9 - 30 years, and demonstrate the non-inferiority of the candidate HPV vaccine manufactured at commercial scale compared with a pilot scale.

结局指标
主要结局
Percentage of participants who seroconvert to HPV-16 and/or HPV-18 at one month post 3rd dose
时间窗: At Month 7
Seroconversion was defined as: For initially seronegative subjects \[antibody titer below (\<) 1:40 prior to vaccination\], antibody titer greater than or equal to (≥) 1:40 after vaccination; For initially seropositive subjects (antibody titer ≥ 1:40 prior to vaccination), antibody titer after vaccination ≥ 4 fold the pre-vaccination antibody titer.
Geometric Mean Titers (GMTs) for HPV-16 and/or HPV-18 at one month post 3rd dose
时间窗: At Month 7
次要结局
- Incidence of solicited adverse events (AEs) after vaccination(0~7 days after each vaccination)
- Incidence of unsolicited AEs after vaccination(0~30 days after each vaccination)
- Incidence of serious adverse events (SAEs)(Month 0 to Month 7)
- Incidence of Treatment-Emergent Adverse Events (TEAE) during 30 days after each dose(0~30 days after each vaccination)
