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.

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.
