简要总结

This study is a single center , randomized ,controlled and open-label phase Ⅳclinical trial of the booster immunization with the third dose of inactivated COVID-19 vaccine(CoronaVac)manufactured by Sinovac Research & Development Co.,Ltd. The purpose of this study is to evaluate the immunogenicity and safety of the third dose of COVID-19 vaccine,inactivated (Vero Cell) co-administration with influenza vaccine and pneumococcal polysaccharide vaccine in healthy population aged 18 years and older.

详细描述

This study is a single center , randomized ,controlled and open-label phase Ⅳclinical trial in healthy adult aged 18 years and older. The purpose of this study is to evaluate the immunogenicity and safety of the third dose of COVID-19 vaccine,inactivated (Vero Cell) co-administration with influenza vaccine and pneumococcal polysaccharide vaccine.The COVID-19 vaccine was manufactured by Sinovac Research &Development Co., Ltd,and the quadrivalent influenza vaccine and 23-valent pneumococcal polysaccharide vaccine(PPV23) were manufactured by Sinovac Biotech Co.A total of 3000 subjects will be enrolled, with 300 aged 18~59years(adult group) and 300 aged 60 years and above(adult group) in the section of immunogenicity and safety of combined immunization ,with 1200 aged 18~59 years(adult group) and 1200 aged 60 years and above(elderly Group) in the section of safety observation study of combined immunization.Each age group will be randomly divided into 3 subgroups of 100 people per group, each subject will receive 1 dose of COVID-19 vaccine, 1 dose of influenza vaccine and 1 dose of pneumonia vaccine in the section of immunogenicity and safety of combined immunization and each age group will be randomly divided into 2 subgroups of 600 people per group, each subject will receive 1 dose of COVID-19 vaccine, 1 dose of influenza vaccine and 1 dose of pneumonia vaccine in the section of safety observation study of combined immunization.
