Brief Summary:
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.
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) . 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.
