Evaluation of Immunogenicity and Safety of Combined Immunization of COVID-19 Vaccine (Produced in Beijing) and PPV23 / IIV4

October 12, 2021 updated by: China National Biotec Group Company Limited

A Randomized, Controlled, Multicenter Phase 4 Clinic Trial to Evaluate the Immunogenicity and Safety of Combined Immunization of Inactivated SARS-CoV-2 Vaccines (Vero Cell) (COVAX) (Produced in Beijing) and 23-valent Pneumococcal Polysaccharide Vaccine (PPV23) or Quadrivalent Inactivated Influenza Vaccine (IIV4)

Subjects will be recruited and divided into 3 groups:

Experimental Group (384 subjects): 1st dose : combined vaccination of COVAX+IIV4, 2nd dose: combined vaccination of COVAX+PPV23; Control Group A (384 subjects): 1st dose: COVAX only, 2nd dose: COVAX only; Control Group B (384 subjects): 1st dose: IIV4 only, 2nd dose: PPV23 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.

Study Overview

Detailed Description

This randomized, parallel, controlled study is designed to evaluate the immunogenicity and safety of simultaneously immunization of COVAX + PPV23 and COVAX + IIV4.

1152 subjects are divided into 3 groups, including 1 experimental group and 2 control groups (control group A and B). Each group includes 384 subjects respectively.

Experimental Group (384 subjects) will receive: 1st dose : combined vaccination of COVAX+IIV4, 2nd dose: combined vaccination of COVAX+PPV23; Control Group A (384 subjects) will receive: 1st dose: COVAX only, 2nd dose: COVAX only; Control Group B (384 subjects) will receive: 1st dose: IIV4 only, 2nd dose: PPV23 only.

Specifically, each group will be divided again. Each 384-subject group is divided again into 2 age-based subgroups: (1) 18-59 years old; (2) ≥60 years old.

Each subgroup includes 192 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.
