Safety and Immunogenicity of Two Doses of aH5N1 Vaccine in Adult and Elderly Subjects With and Without Underlying Medical Conditions
November 3, 2016 updated by: Seqirus
Phase III, Stratified, Randomized, Controlled, Observer-Blind, Multicenter Study to Evaluate the Safety, Tolerability, and Immunogenicity of Two Doses of aH5N1 When Administered to Adult and Elderly Subjects With and Without Underlying Medical Conditions.
Evaluate the safety, immune response and reactogenicity of aH5N1 vaccination in adult (18 through 60 years of age) and elderly (≥61 years of age) subjects with and without underlying medical conditions.

Geometric mean ratios (GMRs) as determined by HI assay
Time Frame: day 43
