Medidas de resultado primarias

Medida de resultado
Medida Descripción
Periodo de tiempo
Number Subjects Who Responded to Two or Three Vaccinations of the MF59-H5N1 Influenza Vaccine
Periodo de tiempo: 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
Periodo de tiempo: 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.
21 days after second and third vaccinations (day 22 and day 43)
Number of Subjects Who Responded to Two Vaccinations of the Seasonal eTIV_a Influenza Vaccines (Strain H1N1)
Periodo de tiempo: 21 days after second vaccination (day 43)

seroconversion: negative pre-vaccination serum (HI titer <10, SRH area =<4 mm^2)/positive post-vaccination titer (HI titer =>10) or at least 50% increase in the SRH area.

Number of Subjects With Immunogenicity Results After the Booster Vaccination Against the MF59-eH5N1 Influenza Vaccine Mixed Extemporaneously With the Seasonal eTIV_a Influenza Vaccine
Periodo de tiempo: 21 days after booster vaccination (day 403)

Booster was given on day 382; seroconversion: negative pre-vaccination serum (HI titer <10, SRH area ≤ 4 mm^2)/positive post-vaccination titer (HI titer ≥10) or at least 50% increase in SRH area; Seroprotection is defined as a HI titer ≥40 and a SRH area ≥25 mm^2.

The number of subjects achieving seroconversion or significant increase and seroprotection were calculated at day 382.
