Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Experimental Group (468 subjects): 1st dose : combined vaccination of COVAX+PPV23, 2nd dose: combined vaccination of COVAX+IIV4; Control Group A (468 subjects): 1st dose: COVAX only, 2nd dose: COVAX only; Control Group B (468 subjects): 1st dose: PPV23 only, 2nd dose: IIV4 only.
Blood samples will be collected 3 times:
before the 1st dose of vaccinatioin; before the 2nd dose of vaccination; 28 days after the 2nd dose of vaccination.
The immunogenicity and safety of both experimental and control groups will be analyzed.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
1404 subjects are divided into 3 groups, including 1 experimental group and 2 control groups (control group A and B). Each group includes 468 subjects respectively.
Experimental Group (468 subjects) will receive: 1st dose : combined vaccination of COVAX+PPV23, 2nd dose: combined vaccination of COVAX+IIV4; Control Group A (468 subjects) will receive: 1st dose: COVAX only, 2nd dose: COVAX only; Control Group B (468 subjects) will receive: 1st dose: PPV23 only, 2nd dose: IIV4 only.
Specifically, each group will be divided again. Each 468-subject group is divided again into 2 age-based subgroups: (1) 18-59 years old; (2) ≥60 years old.
Each subgroup includes 234 subjects respectively. Blood samples will be collected 3 times: (1) before the 1st dose of vaccinatioin; (2) before the 2nd dose of vaccination; (3) 28 days after the 2nd dose of vaccination.
To evaluate the immunogenicity, the investigators will detect and compare the neutralizing antibody levels, the seroconversion rates and antibody geometric mean concentrations.
The safety of all groups will be monitored as well.
