措施说明 |
大体时间 |
|---|---|---|
|
Immunogenicity Endpoint: Geometric Mean Titer (GMT): Geometric Mean of Hemagglutination Inhibition (HI) Antibodies at Day 1 and Day 29
大体时间:Day 1 and Day 29
|
GMTs on Day 1 (prior to vaccination) and Day 29 as determined by HI assay against each of the 4 vaccine strains. No hypothesis testing was performed for the primary immunogenicity objectives. |
Day 1 and Day 29
|
|
Immunogenicity Endpoint: Geometric Mean Fold Increase (GMFI) (HI Assay)
大体时间:Day 1 to Day 29
|
Geometric mean of the fold increase in serum HI titer postvaccination (Day 29) compared to prevaccination (Day 1) for each of the 4 vaccine strains.
|
Day 1 to Day 29
|
|
Immunogenicity Endpoint: Percentages of Subjects With HI Titers ≥1:40 at Day 1 and Day 29
大体时间:Day 1 and Day 29
|
Percentages of subjects with HI titers ≥1:40 at Day 1 and Day 29 for each of the 4 vaccine strains.
|
Day 1 and Day 29
|
|
Immunogenicity Endpoint: Percentage of Subjects With Seroconversion at Day 29 (HI Assay)
大体时间:Day 1 to Day 29
|
Seroconversion is defined as ≥4-fold increase in titer postvaccination in those with prevaccination titer equal to or above the lower limit of quantitation (LLOQ; 1:10), or a postvaccination titer ≥1:40 for subjects with baseline titer below the LLOQ (1:10) for HI antibodies.
|
Day 1 to Day 29
|
|
Immunogenicity Endpoint: GMT Ratio (HI Assay)
大体时间:Day 29
|
The GMT ratio is the geometric mean of the postvaccination HI titer for the investigational vaccine over the geometric mean of the postvaccination HI titer for the licensed IIV vaccine. The Day 29 GMT ratios are calculated for the investigational vaccines with reference to the licensed vaccine, ie, the Day 29 GMT ratios are the ratio of the Day 29 GMTs in the Investigational group (IIV-A Investigational, aIIV-B Investigational, or aIIV-C Investigational) compared with the Day 29 GMTs in the Licensed IIV group (ie, Investigational group/Licensed IIV group). As the licensed vaccine is the reference for the GMT ratio, this parameter is presented as "1" for the Licensed IIV group (ie, Licensed IIV group/Licensed IIV group). |
Day 29
|
|
Solicited Local or Systemic AEs
大体时间:Day 1 through Day 7
|
Number and percentage of subjects with solicited local or systemic AEs for 7 days following vaccination, based on the subject reported data (electronic Diary [eDiary]). No hypothesis testing was performed for the primary safety objectives. |

Severe Solicited Local or Systemic AEs
大体时间:Day 1 through Day 7
|
Number and percentage of subjects with severe solicited local or systemic AEs for 7 days following vaccination, based on the subject reported data (eDiary).

|
Day 1 and Day 29
|
|
Immunogenicity Endpoint: GMFI (MN Assay)

|
Day 1 to Day 29
|
|
Immunogenicity Endpoint: Percentages of Subjects With Seroconversion at Day 29 (MN Assay)
大体时间:Day 1 to Day 29
|
Seroconversion is defined as ≥4-fold increase for subjects with prevaccination MN titers ≥LLOQ (1:10) or as ≥4*LLOQ (1:10) for subjects with prevaccination MN titer <LLOQ.
|
Day 1 to Day 29
|
|
Immunogenicity Endpoint: GMT Ratio (MN Assay)
大体时间:Day 29

The GMT ratio is the geometric mean of the postvaccination HI titer for the investigational vaccine over the geometric mean of the postvaccination HI titer for the licensed IIV vaccine. The Day 29 GMT ratios are calculated for the investigational vaccines with reference to the licensed vaccine, ie, the Day 29 GMT ratios are the ratio of the Day 29 GMTs in the Investigational group (IIV-A Investigational, aIIV-B Investigational, or aIIV-C Investigational) compared with the Day 29 GMTs in the Licensed IIV group (ie, Investigational group/Licensed IIV group).
