        A total of 18000 healthy women aged 18-45 years old were divided into three age groups: 18-26&#xD;
        years old, 27-35 years old, and 36-45 years old. The experimental group and the placebo group&#xD;
        were randomly assigned in a ratio of 1:1. All subjects enrolled in the upper arm deltoid&#xD;
        muscle were injected with 3 doses of test vaccine or placebo according to the 0, 2, and 6&#xD;
        months immunization program.&#xD;

        Introduction: SCT1000 is a recombinant 14-valent human papillomavirus vaccine (insect cell)&#xD;
        that covers all 12 WHO-recognized high-risk oncogenic HPV subtypes Indications are for the&#xD;
        prevention of cervical, vulvar, vaginal, and anal cancers, and genital warts caused by HPV6,&#xD;
        HPV11 and HPV11 in females 9-45 years of age, as well as intraepithelial neoplasia and AIS.&#xD;
        Intraepithelial neoplasia and AIS and genital warts due to HPV6 and HPV11.&#xD;
  &#xD;
        Aim:To evaluate the protective efficacy of 3 doses of HPV vaccine (SCT1000) for the&#xD;
        prevention of HPV type 6,11,16,18,31,33,35,39,45,51,52,56,58,59-associated lesions in healthy&#xD;
        females aged 18-45 years compared with placebo.&#xD;
  &#xD;
        Design: A Multicenter, Randomized, Double-blind, Placebo-controlled phase III Clinical trial&#xD;
        Subject Information: a total of 18000 healthy women aged 18-45 years selected by inclusion&#xD;
        and exclusion criteria.&#xD;
  &#xD;
        Cluster situation: a ratio of 1:1 between the experimental group and the placebo group.&#xD;
  &#xD;
        End point index: relative index with efficacy, safety, and immunogenicity of SCT1000&#xD;

      <masking_description>Blinds for randomized subjects and drug coding blinds will be generated and stored by an independent third party. Immunogenic subgroup blind maintenance: The subgroup information shall not be disclosed to the testing personnel. The serological test results report of the immunogenic subgroup shall be received by non-blind personnel independent of the project team, and the personnel designated by the data management unit shall be responsible for checking the blind data. Before the study is unblinded, the serum results should not be disclosed to the relevant personnel to ensure the blindness of serological test results.&#xD;
  In order to ensure the implementation of the blind method, iDMC will be established in this experiment. At the time of the interim analysis, iDMC was responsible for completing the primary efficacy markers and safety assessment, while the sponsors, investigators, and project staff of the trial remained blind.</masking_description>

  A total of 18000 healthy women aged 18-45 years old were divided into three age groups: 18-26
        years old, 27-35 years old, and 36-45 years old. The experimental group and the placebo group
        were randomly assigned in a ratio of 1:1. All subjects enrolled in the upper arm deltoid
        muscle were injected with 3 doses of test vaccine or placebo according to the 0, 2, and 6
        months immunization program.
  Introduction: SCT1000 is a recombinant 14-valent human papillomavirus vaccine (insect cell)
        that covers all 12 WHO-recognized high-risk oncogenic HPV subtypes Indications are for the
        prevention of cervical, vulvar, vaginal, and anal cancers, and genital warts caused by HPV6,
        HPV11 and HPV11 in females 9-45 years of age, as well as intraepithelial neoplasia and AIS.
        Intraepithelial neoplasia and AIS and genital warts due to HPV6 and HPV11.
  
        Aim:To evaluate the protective efficacy of 3 doses of HPV vaccine (SCT1000) for the
        prevention of HPV type 6,11,16,18,31,33,35,39,45,51,52,56,58,59-associated lesions in healthy
        females aged 18-45 years compared with placebo.
  
        Design: A Multicenter, Randomized, Double-blind, Placebo-controlled phase III Clinical trial
        Subject Information: a total of 18000 healthy women aged 18-45 years selected by inclusion
        and exclusion criteria.
  
        Cluster situation: a ratio of 1:1 between the experimental group and the placebo group.
  
        End point index: relative index with efficacy, safety, and immunogenicity of SCT1000
  allocation: Randomized
  intervention model: Parallel Assignment
  intervention model description: Recombinant 14-Valent Human Papillomavirus Vaccine (Types 6,11,16,18,31,33,35,39, 45,51,52,56,58,59) （Insect Cell）
  primary purpose: Prevention
  masking: Double (Participant, Investigator)
  masking description: Blinds for randomized subjects and drug coding blinds will be generated and stored by an independent third party. Immunogenic subgroup blind maintenance: The subgroup information shall not be disclosed to the testing personnel. The serological test results report of the immunogenic subgroup shall be received by non-blind personnel independent of the project team, and the personnel designated by the data management unit shall be responsible for checking the blind data. Before the study is unblinded, the serum results should not be disclosed to the relevant personnel to ensure the blindness of serological test results.
  In order to ensure the implementation of the blind method, iDMC will be established in this experiment. At the time of the interim analysis, iDMC was responsible for completing the primary efficacy markers and safety assessment, while the sponsors, investigators, and project staff of the trial remained blind.
