Clinical Trial Summary

In order to find the formulation leading to a maximal increase of the immune response while maintaining an acceptable safety profile, this study is designed to evaluate the immunogenicity, safety and reactogenicity of the different formulations of GSK Biologicals' influenza vaccine administered in adults aged 65 years and older compared to Fluarix.

Description:

There are 10 parallel groups: 9 observer blinded groups with subjects 65 years and older receiving an investigational vaccine or Fluarix, and 1 open group with subjects between 18 and 40 years old receiving Fluarix. CMI response will be determined for a subset only.

The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007.
