NCT ID: NCT00309634

Last Updated: 2017-05-10

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE1
• Total Enrollment: 400 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2006-03-27
• Study Completion Date: 2006-10-28

Brief Summary

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.

Eligibility Criteria

Inclusion Criteria

• A male or female between, and including, 18 and 60 years of age at the time of the first vaccination.
• Healthy subjects as established by medical history and clinical examination before entering into the study.
