Study Summary

The purpose of this study is to investigate the safety and immunogenicity of a recombinant hemagglutinin (rHA) influenza vaccine derived from A/Indonesia/05/2005 (H5N1) administered at 3 dose levels in adjuvanted (SE) rHA formulations and 1 dose levels in an un-adjuvanted rHA formulation.

Primary Outcome

Immunogenicity was assessed by measuring the percentage of subjects in each group exhibiting seroconversion on Day 42. The treatment groups that received adjuvanted rHA were evaluated against a non-adjuvanted rHA treatment group for whether they demonstrated seroconversion rates and 95% confidence intervals.

Interventions

  • BIOLOGICAL rHA adjuvant
  • BIOLOGICAL PanBlok
