120 healthy women aged18 to 26 years are in this arm. The first group was 40 subjects to be inoculated with low dose vaccine; After the first low dose group was completed, the safety observation was conducted 7 days after the first dose was completed. If there was no need to suspend / terminate the study, 40 subjects in the group were continued to receive the medium dose vaccine; After the first dose group was completed, the safety observation was 7 days after the first dose was completed. If there was no need to suspend / terminate the test, 40 subjects in the group were inoculated with high dose group. In each dose group SCT1000 : Gardasil®9 : placebo =3:1:1.

A phase 1 random, double blind, positive and placebo control trail was conducted in 120 healthy women in the arm A: 18-26 years old and Arm B: 27-45 years old. The 40 subjects to be inoculated with low, middle, and high dose vaccinefirst in sequence if there was no safety issue. In each dose group SCT1000 : placebo: positive =3:1:1.Two arms can be recruited at the same time. If the DSMB assessment shows that the adverse events of a certain dose group meet the criteria of suspension / termination, the dose group will be suspended / terminated, and the vaccination of this dose group or higher dose group will not be carried out, and the study of other dose groups will continue. If this happens at a low dose, the study will be suspended / terminated.

A Phase I Safty and Immunogenicity Study of SCT1000 in Healthy Women Aged 18 to 45 Years

A Randomized, Double-Blind, Controlled (Positive and Placebo) Phase I Clinical Trial to Estimate Safty and Immunogenicity of the SCT1000 in Healthy Women Aged 18 to 45 Years

Occurrence of local reaction AEs up to 7 days following each dose

Occurrence of systemic AEs up to 7 days following each dose

Occurrence of AEs from dose1 to 30 days after each dose

Occurrence of SAEs from dose1 to 30 days after each dose and from dose1 to 12 months after first dose

Changes in laboratory test indicators (including white blood cell count, lymphocyte count, neutrophils, platelets, hemoglobin, ALT, AST, total bilirubin, fasting blood glucose, creatinine) 3 days after vaccination
