Study Arms:
- Dose A (3.75 µg HA antigen, 0.25 mL) (Type: EXPERIMENTAL): Within each age stratum (4 age strata) subjects will be randomized 1:1 to receive two vaccinations of either Dose A (3.75 µg) or Dose B (7.5 µg) of H1N1 pandemic influenza vaccine at a 21-day interval.
- Dose B (7.5µg HA antigen, 0.5 mL) (Type: EXPERIMENTAL): Within each age stratum (4 age strata) subjects will be randomized 1:1 to receive two vaccinations of either Dose A (3.75 µg) or Dose B (7.5µg) of H1N1 pandemic influenza vaccine at a 21-day interval. A booster vaccination with a licensed seasonal trivalent influenza vaccine for the season 2010/2011 will be administered to at least 30 subjects in each age stratum (who have received Dose B) at 360 days after the first vaccination.

Based on this trial design, predict the completion outcome and termination type (if applicable).
