Brief Summary

This is a multi-center, open, prospective cohort study that aims to investigate the immunogenicity and immune persistence of two different domestically produced bivalent HPV vaccines compared with an imported HPV vaccine in women aged 13-14 years. A total of 3,000 subjects who have completed 2 doses of the domestic bivalent HPV vaccine and 3 doses of the imported HPV vaccine will be recruited from Fujian Maternal and Child Health Hospital as the initiator of the study, and will be recruited from a number of healthcare institutions nationwide. Of these, 1,000 subjects were vaccinated with the domestic bivalent HPV vaccine (Wozehui), 1,000 subjects were vaccinated with the domestic bivalent HPV vaccine (Cecolin), and 1,000 subjects were vaccinated with the imported HPV vaccine. Each subject was enrolled within 30-60 days after the last dose of domestic bivalent HPV vaccine or imported HPV vaccine, and a total of two follow-up visits were conducted 12 months (window period ± 1 month) and 36 months (window period ± 1 month) after the last dose of domestic bivalent HPV vaccine or imported HPV vaccine. In response to the WHO Cervical Cancer Elimination Strategy, domestic bivalent HPV vaccine has been offered free of charge to adolescent females aged 13-14 years, but there is still a lack of evidence comparing the antibody titer levels of domestic HPV vaccine and imported HPV vaccine in younger females. Therefore, we conducted the present immunogenicity study to explore the immunogenicity and immune persistence after vaccination with domestic bivalent HPV vaccine versus imported HPV vaccine in this age group of females.

Detailed Description

The study aims to: 1) Evaluate the immunogenicity of two different domestically produced bivalent HPV vaccines (Wozehui ® and Cecolin ®) versus imported HPV vaccines in adolescent females aged 13-14 years old; 2) Evaluate the immune persistence of two different domestically produced bivalent HPV vaccines (Wozehui ® and Cecolin ®) versus imported HPV vaccines in adolescent females aged 13-14 years old. This study is a multi-center, open, prospective cohort study with a total of 3,000 subjects recruited. According to the HPV vaccine that the participants received in the previous period, they were divided into 1,000 people in the domestic bivalent HPV vaccine group (Wozehui), 1,000 people in the domestic bivalent HPV vaccine group (Cecolin), and 1,000 people in the imported HPV vaccine group. Three immuneogenic blood was collected in all subjects 30-60 days, 12 months (window period ± 1 month) and 36 months (window period ± 1 month) after the last dose of either the domestic bivalent HPV vaccine or the imported HPV vaccine, which was used to perform HPV type 16 and 18 neutralizing antibody testing. The aim of this study was to evaluate the immunogenicity difference between two different domestically produced bivalent HPV vaccines and imported HPV vaccines in adolescent females aged 13-14 years.

Conditions

HPV Infection; HPV Vaccine; Cervical Cancer Prevention

Study Design

• Observational Model Type: COHORT
• Study Time Perspective: PROSPECTIVE

Study Groups

Adolescent females who received their first dose of HPV vaccine at 13-14 years

Adolescent females who completed their last dose of domestic bivalent HPV vaccine or imported HPV vaccine and were between 13 and 14 years of age at the time of the first dose. Two follow-up visits were conducted 12 months (window period ± 1 month) and 36 months (window period ± 1 month) after the last dose of vaccination.

Follow up

Intervention Type: OTHER

Each subject was recruited in 30-60 days after the last dose of domestic bivalent HPV vaccine or imported HPV vaccine, and followed up at 12 months (window period ± 1 month) and 36 months (window period ± 1 month) after the last dose of domestic bivalent HPV vaccine or imported HPV vaccine, with a total of two follow-up visits. At enrollment and both follow-up visits, subjects were required to collect 2 tubes of peripheral venous blood each.

Interventions

Follow up

At enrollment and both follow-up visits, subjects were required to collect 2 tubes of peripheral venous blood each.
