- Registration Number
- NCT06632912
- Lead Sponsor
- National Vaccine and Serum Institute, China
- Brief Summary
This vaccine was jointly developed by Chengdu Institute of Biological Products Co., Ltd. and National Vaccine and Serum Institute, China, is co-sponsoring this clinical trial.
This trial plans to enroll 1,800 female subjects aged 9-26 years, 600 in each of the 18-26 years old 3-dose group, 9-17 years old 3-dose group and 9-14 years old 2-dose group.
All subjects in the 9-14 years old 2-dose group will be injected with 2 doses of the experimental vaccine in the deltoid muscle of the upper arm according to the 0-6 month immunization schedule. Subjects in the non-immune persistence subgroup will need to complete 6 on-site visits (V1-V3, V7-V9) and subjects in the immune persistence subgroup will need to complete 12 on-site visits (V1-V3, V7-V15); All subjects in the 9-17 years old 3-dose group and the 18-26 years old 3-dose group will be injected with 3 doses of the experimental vaccine in the deltoid muscle of the upper arm according to the 0, 2, and 6 month immunization schedule. Subjects in the non-immune persistence subgroup will need to complete 9 on-site visits (V1-V9) and subjects in the immune persistence subgroup will need to complete 15 on-site visits (V1-V15).
