Information provided by (Responsible Party):
Sanofi ( Sanofi Pasteur, a Sanofi Company )
  Purpose
Based on the results from a previous formulation/dosage ranging trial, this phase II multicenter, open trial was designed to determine the safety and immunogenicity of two vaccine formulation/dosages with and without adjuvant 21 days after each vaccination in adults (18 to 60 years and in the elderly (> 60 years) as required by the European Medicines Agency (EMEA) guideline. The antibody persistence until the booster vaccination at 6 or 12 months will also be evaluated.

Condition Intervention Phase
Influenza Orthomyxoviridae Infections Biological: A/H5N1 inactivated, split-virion influenza virus Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)
