    Timeframe: From Day 0 after the first dose of vaccination to 6 months after the thrid dose

    The percentage of participants with Pregnancy Events was assessed

  1. Immunogenicity after receiving 3 doses of 15-HPV vaccine

    Timeframe: Up to 31 days after the third vaccination

    Geometric mean titer (GMT) of anti-vaccine containing corresponding type of neutralizing antibody in subjects aged 18-45 years on the 31-day after the third dose of immunization

  2. Immunogenicity of 15-HPV vaccine

    Timeframe: Up to 31 days after the third vaccination

    Seroconversion rate （SCR）of the anti-vaccine containing the corresponding type of neutralizing antibody on day 31 after total immunization in subjects aged 18-45 years
