Tidsramme |
|---|---|---|
|
Number Subjects Who Responded to Two or Three Vaccinations of the MF59-H5N1 Influenza Vaccine
Tidsramme: 21 days after second and third vaccinations (day 43 and day 403)
|
Seroconversion (serocon.) is defined as negative pre-vaccination serum (titer <10 for HI [Haemagglutination Inhibition], area ≤4 mm^2 for SRH [Single Radial Haemolysis]) / positive post-vaccination titer (titer ≥ 40 for HI, area ≥ 25 mm^2 for SRH). Significant increase in antibody titer is defined as at least a fourfold increase from non-negative pre-vaccination serum (HI ≥ 10) or at least 50% increase in the SRH area. Seroprotection is defined as a HI titer ≥40 and a SRH area ≥25 mm^2. |
21 days after second and third vaccinations (day 43 and day 403)
|
|
Geometric Mean Ratio After Two or Three Vaccinations of the MF59-eH5N1 Influenza Vaccine
Tidsramme: 21 days after second and third vaccinations (day 22 and day 43)
|
Geometric mean Ratio (GMR) was calculated for the haemagglutination inhibition (HI), microneutralization (MN) and single-radial haemolysis (SRH) result as well as the associated 95% confidence intervals.
GMR was calculated as 21 days after second and third vaccinations over day 1.

Geometric Mean Ratio After Two Doses of the Seasonal eTIV_a Influenza Vaccine (Strain H1N1)
Tidsramme: 21 days after second vaccination (day 43)
|
For each vaccine group, the least squares GMRs were calculated for the haemagglutination inhibition (HI) results as well as the associated 95% confidence intervals.
GMR was calculated over day 1.
