What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Hemagglutination Inhibition (HI) Geometric Mean Titers (GMTs) of TIV Group and TIVf Group for All Three Strains, in Healthy Adults Aged ≥50 Years
Time Frame: Day 22
|
Non-inferiority of Postvaccination Hemagglutination Inhibition (HI) Geometric Mean Titers (GMTs) of TIV (Trivalent Subunit Inactivated Influenza Vaccine) Group Over the Corresponding TIVf Group for All Three Strains, three weeks after vaccination (day 22). The upper limit of the two-sided 95% confidence interval (CI) on the ratio of GMTs (GMT TIVf/GMT TIV) should not exceed the non-inferiority margin of 1.5. |
Day 22
|
Percentages of Subjects Achieving Seroconversion (SC) in Antibody Titers in the TIV Group Compared With the Corresponding Percentages of Subjects in the TIVf Group for All Three Strains At Day 22, in Healthy Adults Aged ≥50 Years
Time Frame: Day 22
|
Non-Inferiority was measured as the percentages of subjects who achieved seroconversion in HI titers three weeks (day 22) after vaccination of TIV compared with TIVf, against each of three vaccine strains. Seroconversion is defined as a prevaccination titer <10 and postvaccination HI ≥40 or as a prevaccination titer ≥10 and at minimum four-fold rise in postvaccination antibody titer. The upper limit of the two-sided 95% CI on the difference between the seroconversion rates (Seroconversion TIVf - SeroconversionTIV) should not exceed 10%. |
Day 22
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Evaluation of Percentages of Subjects Who Achieved HI Seroconversion and HI Titer ≥1:40 Against Each of Three Strains After One Vaccination of TIV and TIVf Vaccine
Time Frame: Day 22
|
Percentage of subjects achieving HI seroconversion against each of three vaccine strains was measured three weeks after vaccination of TIV and TIVf vaccine (day 22). Percentage of subjects who achieved HI titer ≥1:40 against each of three vaccine strains was measured three weeks after one vaccination of TIV and TIVf vaccine. According to Center for Biologics Evaluation and Research recommendations (CBER 2007), the criterion for seroconversion is considered met if the lower limit of the two-sided 95% CI for the percentage of subjects with HI seroconversion is ≥40% (<65 years) or ≥30% (≥65 years). As per the CBER criteria, the lower limit of the two-sided 95% CI for the percentage of subjects who achieved HI titer ≥ 1:40 should be ≥70% (<65 years) or ≥60% (≥65 years). |
Day 22
|
Geometric Mean Ratio of Subjects Against Each of Three Strains After One Vaccination of TIV and TIVf Vaccine
Time Frame: Day 22
|
Geometric mean ratio (GMR) of subjects was calculated as the ratio of postvaccination to prevaccination HI GMTs against each of three vaccine strains, three weeks after vaccination of TIV and TIVf vaccine (day 22).
|
Day 22
|
Number of Subjects Who Reported Solicited Local and Systemic Adverse Events After One Vaccination of TIV and TIVf
Time Frame: Day 1 to 7 postvaccination
|
Safety was assessed as the number of subjects who reported solicited local and systemic adverse events from day 1 up to and including day 7 after vaccination of TIV and control.
|
Day 1 to 7 postvaccination
