Brief Summary

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

The primary objective of this study is to evaluate the durability of protection and immuno-persistence of Recombinant Human Papillomavirus Bivalent (Types 16,18) Vaccine administered in females aged 18-45 years.

Detailed Description

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

This is a follow-up study that is based on phase III clinical study of a recombinant human papillomavirus 16/18 bivalent vaccine in females aged 18-45 years (Unique Protocol ID: HPV-PRO-003, Identifiers: NCT01735006). The investigators will recruit people who have participated in phase III clinical study before and to evaluate the durability of protection and immuno-persistence of the bivalent HPV vaccine on 90m and 114m after dose 1.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Vaccine group

Participants in this arm have received 3 doses of HPV 16/18 bivalent vaccine that contains 40μg HPV 16 virus-like particle antigen and 20μg HPV 18 virus-like particle antigen adsorbed in alum-adjuvant.

Recombinant Human Papillomavirus Bivalent (Types 16, 18) Vaccine (Escherichia coli)

Intervention Type BIOLOGICAL

The bivalent HPV-16/18 vaccine was a mixture of two aluminum hydroxide adjuvant-absorbed recombinant L1 VLPs of HPV-16 and HPV-18 expressed in E. coli. A 0.5 ml dose of the bivalent HPV test vaccine comprised 40 μg of HPV-16 and 20 μg of HPV-18 L1 VLPs absorbed with 208 μg of aluminum adjuvant

Control group

Participants in this arm have received 3 doses of HEV vaccine that contains 30μg HEV virus-like particle antigen adsorbed in alum-adjuvant.

No interventions assigned to this group
