Summary

Popular topicClinical study of recombinant Novel Coronavirus vaccine (CHO cell) combined with influenza vaccine. Research purpose:Main purpose:To evaluate the immunogenicity of recombinant Novel Coronavirus vaccine (CHO cells) combined with influenza vaccine in people aged 18 years and over. Secondary purpose:To evaluate the safety of recombinant Novel Coronavirus vaccine (CHO cells) combined with influenza vaccine in people aged 18 years and over. Overall design:An open experimental design was adopted in this study, and 300 subjects were planned to be enrolled. To evaluate the immunogenicity and safety of recombinant Novel Coronavirus vaccine (CHO cells) in combination with influenza vaccine. Study population:The study involved people 18 years of age and older.

Test groups:A total of 300 cases were enrolled. 240 patients in 18-59 years old group, 60 patients in 60 years old group. There were 150 cases in group A, 120 cases in 18-59 years old group, and 30 cases in 60 years old group. There were 150 cases in group B, 120 cases in 18-59 years old group and 30 cases in 60 years old group.

Description

Overall design:An open experimental design was adopted in this study, and 300 subjects were planned to be enrolled. To evaluate the immunogenicity and safety of recombinant Novel Coronavirus vaccine (CHO cells) in combination with influenza vaccine.

Intervention

Group A: one dose of influenza virus split vaccine and one dose of recombinant Novel coronavirus vaccine (CHO cells) in the contralateral arm on day 0, the second dose of recombinant Novel coronavirus vaccine (CHO cells) on day 30, and the third dose of recombinant Novel coronavirus vaccine (CHO cells) on day 60 were given intramuscularly in the upper arm deltoid muscle.

Group B: the first dose of recombinant Novel coronavirus vaccine (CHO cells) was administered on day 0, the second dose of recombinant Coronavirus vaccine (CHO cells) on day 30, the first dose of influenza virus lysate vaccine on day 44, and the third dose of recombinant Coronavirus vaccine (CHO cells) on day 60.

One dose of recombinant Novel Coronavirus vaccine (CHO cells) was administered at 0.5mL each dose, containing 25g nCP-RBD protein. Influenza virus lysis vaccine, one dose at a time, each dose 0.5mL, containing each influenza virus strain hemagglutinin 15g.

Immunogenicity observation:

Evaluation of immunogenicity In group A, about 5.0mL of venous blood was collected for immunogenicity test before the first dose of vaccine, before the second dose of Novel Coronavirus vaccine (CHO cells) and 14 days after the third dose of recombinant Novel Coronavirus vaccine (CHO cells).

In group B, about 5.0mL of venous blood was collected for immunogenicity test before the first dose of vaccine and 14 days after the third dose of recombinant Novel Coronavirus vaccine (CHO cells).

Safety assessment

AE and SAE

All adverse events (AE), all AE at 30 min after each dose of recombinant Novel Coronavirus vaccine (CHO cells) and influenza vaccine, all AE at 0-7 days (both solicitation and non-solicitation AE) and all AE at 8-30 days (non-solicitation AE) were collected; All SAE were collected from the first dose to 1 month after full immunization.

Solicitation AE[the following events occurring within 7 days after vaccination with recombinant Novel Coronavirus vaccine (CHO cells)] :

Inoculation site (local) AE: pain, swelling, induration, redness, rash, pruritus Vital signs: fever Non-inoculated site (whole body) AE: headache, fatigue/fatigue, diarrhea, nausea, vomiting, muscle pain (non-inoculated site), acute allergic reaction, cough

Vital signs and physical examination

All subjects shall have their axillary body temperature checked daily during the screening period, before the subsequent dose of recombinant Novel Coronavirus vaccine (CHO cells), and within 7 days after each dose of recombinant Novel Coronavirus vaccine (CHO cells); Subjects in group B will have their armpit temperature measured before influenza vaccination (the day of vaccination).

All subjects underwent physical examination (skin and cardiopulmonary auscultation) and blood pressure measurement during the screening period.

Pregnancy event

Urine pregnancy test should be performed on women of childbearing age before each dose of recombinant Novel Coronavirus vaccine (CHO cells); Women of childbearing age in group B should have a urine pregnancy test prior to influenza vaccination.

Pregnancy events occurring within 1 month from the first dose of vaccine to full immunization were collected.

ADE/VED risk monitoring

After vaccination (at least 1 dose of trial vaccine) (at each visit), subjects will be reminded to contact the investigator in case of fever and/or respiratory symptoms (e.g., dyspnea, sore throat, etc.), suspected or confirmed cases of COVID-19 occurring during the study period. If the subjects are suspected or confirmed to be infected with SARS-COV-2 during the trial period, they should go to a local designated hospital for diagnosis and treatment. A detailed case-by-case investigation is required for confirmed cases. In the event of severe COVID-19 infection or death, an expert meeting should be held to evaluate ADE/VED.
