| Measure | Time 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 vaccine dose. 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 a 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.;Serum IgG level for SARS-CoV-2 N, S1-RBD antigens. Timepoint: on days zero, second injection day, two and four weeks after second injection and at 3, 6 months after the first vaccination. Method of measurement: ELISA method. | — |

Timepoint: Two weeks after the second dose of the vaccine to study end. Method of measurement: PCR test.;Neutralizing antibody activity. Timepoint: on days zero, second injection day, two and four weeks after second injection and at 3, 6 months after the first vaccination. Method of measurement: Conventional SARS-CoV-2 virus neutralizing antibody test using a biosafety level III.;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), U/A, Urine protein, Urine glucose, Urine RBC, IL-6. Timepoint: Seven days after each vaccination, IL-6 will be measured at day zero as well. Method of measurement: Each test will be performed using the appropriate kit. | — |
