Brief Summary
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.

- Masking Details
- 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.
