Influenza Clinical Trial
Official title:
Observer-blind Monocentric Study in Adults Aged Between 18-60 Years to Evaluate Reactogenicity and Immunogenicity of 1 and 2 Administrations of Pandemic Monovalent Influenza Vaccines Administered at Different Antigen Doses and Adjuvanted or Not
Today, the leading contender for the next pandemic of influenza is H5N1, a strain of avian virus. Prevention and control of a pandemic will depend on the rapid production and worldwide distribution of specific pandemic vaccines. Candidate 'pandemic-like' vaccines must be developed and tested in clinical trials to determine the most optimal formulation and the best vaccination schedule.This study is designed to test in healthy adults aged between 18-60 years the reactogenicity and immunogenicity of one and two administrations of a candidate pandemic H5N1 vaccine formulated from Split Virus. The vaccines contain different antigen doses . For each dose, adjuvanted vaccine will be compared to the plain vaccine in order to detect the optimal formulation for immunization against the H5N1 influenza strain.
