Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a phase II clinical study of the novel recombinant HPV 16/18 bivalent vaccine expressed in E. coli.

The primary purpose of this study is to evaluate which dosage of the HPV vaccine can induce higher antibody and at the same time caused less adverse events.

The secondary purpose of this study is to to evaluate the safety and immunopersistence of the study vaccine.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Totally 1600 healthy women of 18-25 years of age were enrolled. The participants were randomly stratified into 4 groups and receive different dosage of human papillomavirus (HPV) vaccine or placebo administered intramuscularly according to a 0-1-6 month schedule. The women were actively monitored for adverse events for 1 month after each injection. Severe adverse events during the trial were followed up. Serum samples from all the subjects would be collected on day 0, 7m, 24m, 48m and 72m to evaluate the immunogenicity and immuno-persistency.
