No intervention was implemented in this study. Participants who have participated in the immunobridging clinical trial of the bivalent HPV vaccine (Unique Protocol ID:HPV-PRO-006,Identifiers: NCT02562508) and were aged 9-17 years at the time of enrollment, and have received at least one dose of the vaccine were recruited as the vaccine group for long-term effectiveness evaluation.

No intervention was implemented in this study. Participants with no previous HPV vaccination history were recruited as the control group for long-term effectiveness evaluation.

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.

The primary objective of this study is to evaluate the protective efficacy against future infections of HPV types 16/18 or related diseases and immuno-persistence (type specific IgG antibody) of the bivalent HPV vaccine in young female populations aged 9-17 years.

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) . This study proposes to conduct a prospective cohort study based on the cohort population from the immunobridging clinical trial of the bivalent HPV vaccine (Unique Protocol ID:HPV-PRO-006,Identifiers: NCT02562508) . By matching control groups according to factors such as age and education level, and through long-term follow-up, this research aims to elucidate the protective efficacy of the bivalent HPV vaccine against future infections of HPV types 16/18/31/33/45 or related diseases in young female populations aged 9-17 years. Additionally, the study will evaluate the persistence of vaccine-induced antibodies, investigate the potential for type replacement/competition phenomena post-vaccination and assess oral HPV infections in the cohort population.

Participants in this arm have received 60μg of HPV 16/18 bivalent vaccine according to 3 doses of HPV 16/18 bivalent vaccine

Participants in this arm have received 60μg of HPV 16/18 bivalent vaccine according to 2 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

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).

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
