Primary Outcome Measures
NameTimeMethod
Percentage of subjects with an HI titer ≥1:40day 43
Percentage of subjects achieving seroconversionday 43

Seroconversion is defined as hemagglutination inhibition (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 \[day 1 HI titer ≥1:10\])

Geometric mean ratios (GMRs) as determined by HI assayday 43
Solicited and unsolicited adverse eventsday 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 Outcome Measures
NameTimeMethod
GMTs as determined by SRHday 1

Serial radial haemolysis (SRH) assay: homologous antibody responses to aH5N1 vaccine 3 weeks after first and second vaccinations (day 22 and day 43) according to CHMP immunogenicity criteria in adult and elderly subjects who are healthy or with underlying medical condition

Geometric mean titers (GMTs) as determined by HIday 22 (3 weeks after the first vaccination)

HI assay: homologous antibody responses to aH5N1 vaccine 3 weeks after first vaccination (day 22) according to CHMP immunogenicity criteria in adult and elderly subjects who are healthy or with underlying medical condition

Percentage of subjects with geometric mean area ≥25 mm2day 22
Geometric mean ratios (GMRs) as determined by SRHday 43 (3 weeks after the second vaccination)
Percentage of subjects with an HI titer ≥1:40day 1
Percentage of subjects achieving seroconversionday 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 \[SRH area \>3.997 mm2\])
