Outcome

Type Measure Description Time frame Safety issue
Primary Assess the Proportion of Subjects in Each Dose Group Achieving Seroconversion and Seroprotection for HI Antibody Titer Through Day 28. Seroconversion is defined as either 1) baseline HI titer < 1:10 and a post-vaccination HI titer = 1:40, or 2) baseline HI titer = 1:10 and a minimum four-fold rise. Seroprotection is defined as a post-vaccination HI antibody titer = 1:40. FDA/EMEA criterion for seroconversion was to meet or exceed 40%. FDA/EMEA criterion for seroprotection was to meet or exceed 70%. Day 28
Secondary Safety of A/H5N1 Vaccine IM Injection With and Without an LT Adjuvant Patch 6 months
Secondary Evaluate Treatment Group HI Responses Against US FDA Guidance for Industry: Clinical Data Needed to Support the Licensure of Pandemic Influenza Vaccines (May 2007) and EMA CPMP/BWP/214/96 Criteria for Immunogenicity Day 28
