Outcome Measures

Primary Outcomes (1)

  • Number of subjects achieving antibody levels to A/H1N1/California/07/2009 virus that meet the definition of seroprotection and seroconversion at 21 days after the second vaccination

    42 days

Study Arms (3)

Cohort 1/Dose Level A

EXPERIMENTAL

Subjects in Cohort 1 will be randomized 1:1 to receive two vaccinations of Dose A or Dose B of H1N1 pandemic influenza vaccine at a 21-day interval.

Biological: H1N1 pandemic influenza vaccine (whole virion, Vero Cell-derived, inactivated)

Cohort 1/Dose B

EXPERIMENTAL

Subjects in Cohort 1 will be randomized 1:1 to receive two vaccinations of Dose A or Dose B of H1N1 pandemic influenza vaccine at a 21-day interval.

Biological: H1N1 pandemic influenza vaccine (whole virion, Vero Cell-derived, inactivated)

Cohort 2/Dose C

EXPERIMENTAL

A second cohort may be enrolled with all subjects in this cohort receiving two vaccinations of Dose C of H1N1 pandemic influenza vaccine at a 21-day interval.

Biological: H1N1 pandemic influenza vaccine (whole virion, Vero Cell-derived, inactivated)

Interventions

Two injections at a 21-day interval (Days 1 and 22)
