Also called There is no other Intervention in this study
The bivalent HPV-16/18 vaccine was a mixture of two aluminum hydroxide adjuvant-absorbed recombinant L1 VLPs of HPV-16 and HPV-18 expressed in E. coli. A 0.5 ml dose of the bivalent HPV test vaccine comprised 40 μg of HPV-16 and 20 μg of HPV-18 L1 VLPs absorbed with 208 μg of aluminum adjuvant
| Study group | Role | What they receive |
|---|---|---|
| Vaccine group | Participants in this arm have received 3 doses of HPV 16/18 bivalent vaccine that contains 40μg HPV 16 virus-like particle antigen and 20μg HPV 18 virus-like particle antigen adsorbed in alum-adjuvant.

| Control group | Participants in this arm have received 3 doses of HEV vaccine that contains 30μg HEV virus-like particle antigen adsorbed in alum-adjuvant. |
What is being measured
The primary outcome is the main question the study is designed to answer.

To observe the number of Subjects With Histopathologically-confirmed CIN2+ and/or VIN2+ and/or VaIN2+ Associated With HPV-16 and/or -18 Cervical Infection on 90m and 114m after dose 1
Measured: expected 2-3 years
Number of Subjects With HPV-16 and/or -18 persistent cervical infection(6-month+ definition) on 90m and 114m after dose 1
To detect the HPV16 and HPV18 DNA on the gynecological specimens ( Cervical exfoliated cell specimens and biopsy specimens) collected from the subjects
Measured: expected 2-3 years
