Immuno-persistence Study of a Recombinant Human Papillomavirus 16/18 Bivalent Vaccine in Preadolescent Girls (54m)

January 24, 2023 updated by: Jun Zhang

Immuno-persistence Study of A Bivalent Human Papillomavirus (Type 16, 18) Recombinant Vaccine (E.Coli) in Healthy Female Subjects Aged 9 to 17 Years

The primary objective of this study is to evaluate the immuno-persistence (type specific IgG antibody) of the tested vaccine administered in girls aged 9-17 years,comparing to young healthy adults of 18-26 years who received the standard 3-dose schedule (0,1,6 months).

Study Overview

Detailed Description

This is a follow-up study that is based on the bridging study of a recombinant human papillomavirus 16/18 bivalent vaccine in preadolescent girls(Unique Protocol ID:HPV-PRO-006,Identifiers: NCT02562508) .The investigators will recruit people who have participated in bridging study before and collect their serum samples to test the seroprevalence and geometric mean concentrations of anti-HPV16 and anti-HPV18 antibody on 54 months after dose 1

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
9-17y (0,1,6m)
Participants in this arm have received 60μg of HPV 16/18 bivalent vaccine according to 3 doses of HPV 16/18 bivalent vaccine
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
Other Names:
  • There is no other Intervention in this study
