To evaluate immunogenicity, measured by seroprotection (defined as percentage of subjects achieving a hemagglutination inhibition [HI] titer (> or = 40) and by percentage of subjects achieving seroconversion (defined as negative pre-vaccination serum (<10)/
post-vaccination serum (> or = 40) or significant increase (defined as at least a fourfold increase in titer from non-negative pre-vaccination serum (> or = 10), of
one dose of Agrippal influenza vaccine, administered to healthy adults aged 18 to 64
years according to the CBER Guidance for Industry issued in May 2007.
To evaluate safety and tolerability of:
1. Two doses of either Agrippal or Fluvirin, administered four weeks apart to healthy children aged 3 to 8 years

One dose of either Agrippal® or Fluvirin® influenza vaccine, administered to healthy children/adolescents aged 9 to 17 years.
