Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Rate of normal/abnormal results in clinical laboratory tests(Platelet, Cl, etc.) during screening visit and close-out visit | Screening visit(0-14 days prior to vaccination)/close-out visit(21-28 days after vaccination) | Comparisons within each group between pre-/post- vaccination were summarized and presented. |
| Body temperature at each visit | 0-14 days prior to vaccination/day of vaccination/3-7 days after vaccination/21-28 days after vaccination | Comparisons within each group between pre-/post- vaccination were summarized and presented. |
| Rate of normal/abnormal results in Electrocardiogram (ECG) (ventricular rate, PR interval, QRS, QT, and QTc) collected during screening visit and close-out visit | Screening visit(0-14 days prior to vaccination)/close-out visit(21-28 days after vaccination) | Comparisons within each group between pre-/post- vaccination were summarized and presented. |
| Rate of normal/abnormal results in physical examination at each visit | 0-14 days prior to vaccination/day of vaccination/3-7 days after vaccination/21-28 days after vaccination | Comparisons within each group between pre-/post- vaccination were summarized and presented. |
| Incidence rate of solicited local adverse events (AEs) | Within 21 days after vaccination | All AEs were classified and analyzed according to its severity and causality. The number and percentage of subjects with AEs were analyzed. Incidence rate, 95% confidence interval as well as number of occurrences were calculated. |
| Incidence rate of solicited systemic AEs | Within 21 days after vaccination | All AEs were classified and analyzed according to its severity and causality. The number and percentage of subjects with AEs were analyzed. Incidence rate, 95% confidence interval as well as number of occurrences were calculated. |
| Incidence rate of unsolicited AEs | Within 21 days after vaccination | All AEs were classified and analyzed according to its severity and causality. The number and percentage of subjects with AEs were analyzed. Incidence rate, 95% confidence interval as well as number of occurrences were calculated. |
| Pulse rate at each visit | 0-14 days prior to vaccination/day of vaccination/3-7 days after vaccination/21-28 days after vaccination | Comparisons within each group between pre-/post- vaccination were summarized and presented. |
| Blood pressure(systolic/diastolic) at each visit | 0-14 days prior to vaccination/day of vaccination/3-7 days after vaccination/21-28 days after vaccination | Comparisons within each group between pre-/post- vaccination were summarized and presented. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Geometric Mean Ratio (GMR) measured by pre-/post-vaccination HI titer[Immunogenicity] | 21-28 days after vaccination | The mean increase in geometric mean HI titer |
| Seroprotection rate measured by post-vaccination HI titer[Immunogenicity] | 21-28 days after vaccination | The proportion of subjects with post-vaccination HI titers of ≥1:40 |
| Seroconversion rate measured by pre-/post-vaccination Haemagglutination Inhibition (HI) titer[Immunogenicity] | 21-28 days after vaccination | The proportion of subjects achieving one of the following conditions; i)If the pre-vaccination HI titer were \<1:10, subjects achieving an HI titer ≥1:40 after vaccination ii)If the pre-vaccination HI titers were ≥1:10, subjects with a minimum 4-fold rise in HI titer |
