Outcome Measures

Primary Outcomes (2)

  • Number of Subjects With CIN2+ and/or VIN2+ and/or VaIN2+ Associated With HPV-16 and/or -18 Cervical Infection on 90m and 114m after dose 1

    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

    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

    expected 2-3 years

Study Arms (2)

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.

Biological: Recombinant Human Papillomavirus Bivalent (Types 16, 18) Vaccine (Escherichia coli)

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.

Interventions

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

You may qualify if:

  • Participants who participated in the Phase III clinical study of a recombinant human papillomavirus 16/18 bivalent vaccine in females (Unique Protocol ID: HPV-PRO-003, Identifiers: NCT01735006) and received at least one dose;
  • Participants can fully understand the study content and sign an informed consent form;
  • Able to comply with the requests of the study;

You may not qualify if:

  • Participants used other HPV vaccine products (including both marketed and unmarketed vaccines) since participating in the Phase III clinical study.
  • According to the investigator's judgment, there might be some medical, psychological, social or occupational factors which might impact on the individual to obey the protocol or sign the informed consent;
