Zeitfenster |
---|---|---|
Percentages Of Subjects Who Achieved HI Titer ≥40 After One Vaccination of Cell Culture-derived (cTIV) or Egg-derived (TIV) Influenza Subunit Vaccines
Zeitfenster: Before vaccination (day 1) and three weeks after vaccination (day 22)
|
Immunogenicity was measured as the percentage of adults (≥18 to ≤60 years) and elderly (≥61 years) achieving HI titers ≥40 at baseline (day 1) and three weeks (day 22) after one vaccination of cTIV or TIV vaccine for each of three vaccine strains, evaluated using the hemagglutination inhibition (HI) egg-derived antigen assay. In compliance with the requirements of the EMEA recommendations (CPMP/BWP/2490/00, CPMP/BWP/214/96), this criterion is met if the percentage of subjects achieving HI titers ≥40 is >70% in the ≥18 to ≤60 years of age group or >60% in the ≥61 years of age group. |
Before vaccination (day 1) and three weeks after vaccination (day 22)
|
Percentages Of Subjects Who Achieved Seroconversion Or Significant Increase In HI Titer After One Vaccination of cTIV or TIV
Zeitfenster: Three weeks after vaccination (day 22)
|
Seroconversion or significant in HI titer is defined as the percentage of subjects with a prevaccination HI titer <10 (negative) to a postvaccination titer ≥40; or in subjects with prevaccination HI titer ≥10, at least a 4-fold increase in postvaccination HI titer.
In compliance with the requirements of the EMEA recommendations (CPMP/BWP/2490/00, CPMP/BWP/214/96), the criterion is met if the percentage of subjects achieving seroconversion/significant increase is >40% in the ≥18 to ≤60 years of age group or >30% in the ≥61 years of age group.
|
Three weeks after vaccination (day 22)
|
Geometric Mean Ratio of Subjects After One Vaccination of cTIV or TIV
Zeitfenster: Three weeks after vaccination (day 22)
|
Immunogenicity was measured as the geometric mean ratio (GMR), calculated as the ratio of postvaccination to prevaccination HI Geometric Mean Titers (GMTs), three weeks after (day 22) one vaccination of cTIV or TIV.
In compliance with the requirements of the EMEA recommendations (CPMP/BWP/2490/00, CPMP/BWP/214/96), this criterion is met if the GMR (day 22/day 1) in HI antibody titer is >2.5 in the ≥18 to ≤60 years of age group or >2.0 in the ≥61 years of age group.

Three weeks after vaccination (day 22)
