Primary Outcome Measures:
  • Number Subjects Who Responded to Two or Three Vaccinations of the MF59-H5N1 Influenza Vaccine [ Time Frame: 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.


  • Geometric Mean Ratio After Two or Three Vaccinations of the MF59-eH5N1 Influenza Vaccine [ Time Frame: 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.

  • Number of Subjects Who Responded to Two Vaccinations of the Seasonal eTIV_a Influenza Vaccines (Strain H1N1) [ Time Frame: 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.

    Seroprotection is defined as a HI titer ≥40 and a SRH area ≥25 mm^2.


  • Number of Subjects Who Responded to Two or Three Vaccinations of the Seasonal eTIV_a Influenza Vaccines (Strain H3N2) [ Time Frame: 21 days after second and third vaccinations (day 43 and day 403) ]

    seroconversion (serocon.): 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.

    Seroprotection is defined as a HI titer ≥40 and a SRH area ≥25 mm^2.


  • Number of Subjects Who Responded to Two or Three Vaccinations of the Seasonal eTIV_a Influenza Vaccines (Strain B) [ Time Frame: 21 days after second and third vaccinations (day 43 and day 403) ]

    seroconversion (serocon.): 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.

    Seroprotection is defined as a HI titer ≥40 and a SRH area ≥25 mm^2.


  • Geometric Mean Ratio After Two Doses of the Seasonal eTIV_a Influenza Vaccine (Strain H1N1) [ Time Frame: 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.

  • Geometric Mean Ratio After Two or Three Vaccinations of the Seasonal eTIV_a Influenza Vaccine (Strain H3N1) [ Time Frame: 21 days after second and third vaccinations (day 43 and day 403) ]
    For each vaccine group, the least squares GMRs were calculated for the haemagglutination inhibition (HI) results for each time point of the study, as well as the associated 95% confidence intervals. GMR was calculated over day 1.

  • Geometric Mean Ratio After Two or Three Vaccinations of the Seasonal eTIV_a Influenza Vaccine (Strain B) [ Time Frame: 21 days after second and third vaccinations (day 43 and day 403) ]
    For each vaccine group, the least squares GMRs were calculated for the haemagglutination inhibition (HI) results for each time point of the study, as well as the associated 95% confidence intervals. GMR was calculated over day 1.


Secondary Outcome Measures:
  • Number of Subjects Reporting Local and Systemic Reactions by Vaccination [ Time Frame: 21 days after second and third vaccinations (day 43 and day 403) ]
    The evaluate the safety of the administration of two or three vaccinations of MF59-eH5N1 influenza vaccine, either given sequentially, concomitantly or mixed extemporaneously with seasonal eTIV_a influenza vaccine.

  • 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 [ Time Frame: 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.


  • Geometric Mean Ratio After the Booster Vaccination Against the MF59-eH5N1 Influenza Vaccine Mixed Extemporaneously With the Seasonal eTIV_a Influenza Vaccine [ Time Frame: 21 days after booster vaccination (day 403) ]
    For each vaccine group, the least squares GMRs were calculated for the HI and SRH results for each time point of the study, as well as the associated 95% confidence intervals. GMR was calculated over day 382 for all time points for the booster dose.
