Tidsramme |
---|---|---|
Percentage of Subjects With Single Radial Hemolysis (SRH) Areas ≥25mm2, Against Each of Three Vaccine Strains After Receiving One Dose of TIVc
Tidsramme: Day 22 (vaccination is on day 1)
|
Immunogenicity was assessed in terms of percentages of subjects in both age groups with SRH areas ≥25mm2 against each of the three vaccine strains, three weeks after receiving one dose of TIVc. The related European (CHMP) criterion for the assessment of immunogenicity is met if the percentage of subjects achieving post vaccination SRH areas ≥ 25mm2 is >70% for adults aged 18 to ≤60 years and >60% for subjects aged ≥61 years. |
Day 22 (vaccination is on day 1)
|
Percentages of Subjects With Seroconversion or Significant Increase in SRH Area, Against Each of Three Vaccine Strains After Receiving One Dose of TIVc
Tidsramme: Day 22 (vaccination is on day 1)
|
Immunogenicity was assessed in terms of percentages of subjects in both age groups achieving seroconversion or significant increase by SRH area against each of the three vaccine strains ,three weeks after receiving one dose of TIVc. Seroconversion is defined as percentage of subjects with a pre-vaccination SRH area ≤4mm2 achieving a post-vaccination SRH area ≥25 mm2. Significant increase is defined as percentage of subjects with a pre-vaccination SRH area >4mm2 achieving at least 50% increase in post-vaccination SRH area. The related European (CHMP) criterion for the assessment of immunogenicity is met if the percentage of subjects achieving post vaccination SRH areas ≥ 25mm2 is >40% for adults aged 18 to ≤60 years and >30% for subjects aged ≥61 years. |
Day 22 (vaccination is on day 1)
|
Geometric Mean Ratio of Post Vaccination Versus Pre Vaccination Geometric Mean Areas (GMAs), After One Dose of TIVc
Tidsramme: Day 22/day 1
|
The antibody responses were evaluated in terms of GMRs of post vaccination GMAs to pre vaccination GMAs against each of the three vaccine strains, three weeks after receiving one dose of TIVc The related European (CHMP) criterion for the assessment of immunogenicity is met if the GMR day 22/day 1 is >2.5 for adults aged 18 to ≤60 years and > 2.0 in for subjects aged ≥61 years.

Percentage of Subjects With Haemagglutination Inhibition (HI) Titers ≥40, Against Each of Three Vaccine Strains After Receiving One Dose of TIVc
Tidsramme: Day 22 (vaccination is on day 1)
|
Immunogenicity was assessed in terms of percentages of subjects in both age groups with HI titers ≥40, against each of the three vaccine strains, three weeks after receiving one dose of TIVc. The related European (CHMP) criterion for the assessment of immunogenicity is met if the percentage of subjects achieving HI titers ≥ 40 is >70% for adults aged 18 to ≤60 years and >60% for subjects aged ≥61 years. |

|
Percentages of Subjects With Seroconversion or Significant Increase in HI Antibody Titers After Receiving One Dose of TIVc
Tidsramme: Day 22 (vaccination is on day 1)
|
Immunogenicity was assessed in terms of percentages of subjects in both age groups achieving seroconversion or significant increase in HI antibody titers after receiving one dose of TIVc. Seroconversion is defined as percentage of subjects with a pre-vaccination HI titer <10 to a post-vaccination titer ≥40. Significant increase is defined as percentage of subjects with a pre-vaccination HI titer >10 to at least a 4-fold increase in post-vaccination HI antibody titers. The related European (CHMP) criterion for the assessment of immunogenicity is met if >40 % for adults aged 18 to ≤60 years and >30% for subjects aged ≥61 years achieve seroconversion or significant increase in post-vaccination HI titers. |
Day 22 (vaccination is on day 1)
|
Geometric Mean Ratio of Post Vaccination Versus Pre Vaccination HI Antibody Titers, Against Each of Three Vaccine Strains After Receiving One Dose of TIVc
Tidsramme: Day 22/day 1
|
The antibody responses following one dose of TIVc were evaluated in terms of GMRs of post vaccination against pre vaccination geometric mean HI titers against each of the three vaccine strains, three weeks after receiving one dose of TIVc. The related European (CHMP) criterion for the assessment of immunogenicity is met if the GMR day 22/day 1 is >2.5 for adults aged 18 to ≤60 years and > 2.0 for subjects aged ≥61 years. |
Day 22/day 1
|
Number of Subjects Reporting Solicited Adverse Events After Receiving One Dose of TIVc
Tidsramme: Day 1 to Day 4 post-vaccination
|
The number of adult and elderly subjects reporting solicited local and systemic adverse events and other solicited adverse events after receiving one dose of TIVc are reported.
|
Day 1 to Day 4 post-vaccination
|
Number of Subjects Reporting Unsolicited Adverse Events After Receiving One Dose of TIVc
Tidsramme: Day 1 through Day 22 post-vaccination
|
The number of subjects in both age groups reporting any unsolicited AEs (between Day 1 to 4), serious adverse events (SAEs), medically attended AEs, AEs leading to premature withdrawal (throughout the study period), after receiving one dose of TIVc is reported.
