Safety and Immunogenicity of an Intramuscular Pandemic Influenza Vaccine in Adults and the Elderly
January 10, 2014 updated by: Sanofi Pasteur, a Sanofi Company
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.
