Design outcomes

Primary

MeasureTime frame
Abnormal vital signs and anaphylactic reactions immediately after vaccination. Vital signs include body temperature, Respiratory rate, heart rate, systolic and diastolic blood pressure before and immediately after vaccination. Timepoint: In the first three hours after each vaccination. Method of measurement: Sublingual temperature is measured using a digital thermometer. Heart rate and respiratory rate will be counted by the research staff in one minute. Blood pressure will be measured using a digital sphygmomanometer in sitting position.;Local adverse events within the first week post-vaccination including pain, tenderness, erythema and redness, and swelling and stiffness. Timepoint: In the first seven days after each vaccine dose. Method of measurement: Daily telephone contacts by the research team for seven days.;Systemic adverse event within the first week post-vaccination including nausea and vomiting, diarrhea, headache, fatigue, muscle pain, and other illnesses or clinical complications. Timepoint: In the first seven days after each vaccine dose and then monthly for up to six months. Method of measurement: Telephone contacts by the research team.;Abnormal laboratory findings including Hemoglobin, WBC, Lymphocytes cell, Neutrophils, Eosinophils, Platelets, ESR, CRP, LDH,CPK, RT-PCR for SARS-CoV-2, Sodium, Potassium, BUN , Creatinine, Alkaline phosphatase, ALT, AST, Bilirubin (total), Uric Acid, U/A, Urine protein, Urine glucose, Urine RBC. Timepoint: Seven days after each vaccination. Method of measurement: Each test will be performed using the appropriate kit.

Secondary

MeasureTime frame

Timepoint: Up to six months after the last dose of the vaccine. Method of measurement: Monthly follow-up by the research team.;Occurrence of Covid-19 disease. Timepoint: Two weeks after the second dose of the vaccine. Method of measurement: PCR test.;Serum IgG level for SARS-CoV-2 N and S antigens. Timepoint: In the vaccination schedule 0-14: on days zero, 7, 14, 28, 42, 72 and months 3, 6. In the vaccination schedule 0-21: on days zero, 7, 14, 21, 35, 49 and months 3, 6. Method of measurement: ELISA method.;Neutralizing antibody activity. Timepoint: In the vaccination schedule 0-14: on days zero, 14, 28, 42 and months 3, 6. In the vaccination schedule 0-21: on days zero, 21, 35, 49 and months 3, 6. Method of measurement: Conventional SARS-CoV-2 virus neutralizing antibody test.;Cell-mediated immunity and safety of the immune response. Timepoint: In the vaccination schedule 0-14: on days zero, 14, 28, 42 and months 3, 6. In the vaccination schedule 0-21: on days zero, 21, 35, 49 and months 3, 6. This outcome will be measured on day zero and two weeks after the second injection for all volunteers and at other time points for 20% of the participants.
