Primary Outcome Measures

Name	Time	Method
Percentage of subjects achieving seroconversion*	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.
Geometric mean ratios (GMRs) as determined by HI assay	day 43
Percentage of subjects with an HI titer ≥1:40	day 43
Solicited and unsolicited adverse events	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.

Geometric Mean Ratio as determined by Single Radial Hemolysis	Day 43
Percentage of subjects achieving seroconversion determined by HI	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
Percentage of subjects achieving seroconversion determined by SRH	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
