Primary outcomes

  1. Percentage of subjects achieving seroconversion*

    Time frame: day 43

    *seroconversion: (defined as HI ≥1:40 for subjects who were seronegative at baseline [day 1 HI titer <1:10] or a minimum 4-fold increase in HI titer for subjects who were seropositive at baseline [day 1 HI titer

    ≥1:10]) on day 43.

  2. Geometric mean ratios (GMRs) as determined by HI assay

    Time frame: day 43

  3. Percentage of subjects with an HI titer ≥1:40

    Time frame: day 43

  4. Solicited and unsolicited adverse events

    Time frame: day 202

    In pooled age groups 18 years of age and older subjects who are healthy or with underlying medical condition who have received aTIV or aH5N1 vaccine.

Secondary outcomes

  1. Geometric mean titers as determined by Hemagglutination Inhibition

    Time frame: Day 1

  2. Geometric mean titers as determined by Hemagglutination Inhibition

    Time frame: Day 22

  3. Geometric mean titers as determined by Hemagglutination Inhibition

    Time frame: Day 43

  4. Geometric mean titers as determined by Single Radial Hemolysis

    Time frame: Day 1

  5. Geometric mean titers as determined by Single Radial Hemolysis

    Time frame: Day 22

  6. Geometric mean titers as determined by Single Radial Hemolysis

    Time frame: Day 43

  7. Geometric Mean Ratio as determined by Hemagglutination Inhibition

    Time frame: Day 22

  8. Geometric Mean Ratio as determined by Hemagglutination Inhibition

    Time frame: Day 43

    Time frame: Day 43

  11. Percentage of subjects achieving seroconversion determined by HI

    Time frame: Day 22

    seroconversion is defined as HI ≥1:40 for subjects who were seronegative at baseline [day 1 HI titer <1:10] or a minimum 4-fold increase in HI titer for subjects who were seropositive at baseline [day 1 HI titer ≥1:10]) on days 22

  12. Percentage of subjects achieving seroconversion determined by SRH

    Time frame: Day 22

    seroconversion (defined as SRH area ≥25 mm2 for subjects who were seronegative at baseline [day 1 SRH area ≤3.997 mm2] or a significant increase [at least 50% increase] in SRH area for subjects who were seropositive at baseline [SRH area >3.997 mm2]) on days 22, 43

  13. Percentage of subjects achieving seroconversion determined by SRH

    Time frame: Day 43

    seroconversion is defined as SRH area ≥25 mm2 for subjects who were seronegative at baseline [day 1 SRH area ≤3.997 mm2] or a significant increase [at least 50% increase] in SRH area for subjects who were seropositive at baseline [SRH area >3.997 mm2]) on days 22, 43

  14. Percentage of subjects with an HI titer ≥1:40

    Time frame: Day 1

  15. Percentage of subjects with an HI titer ≥1:40
