A Phase 3 Randomized, Observer-Blind, Multi-center, Controlled Study to Evaluate Safety, Immunogenicity, and Lot-to-Lot Consistency of an Adjuvanted Cell Culture-Derived, H5N1 Subunit Influenza Virus Vaccine in Healthy Adult Subjects ≥18 Years of Age
In Brief
A Phase 3 clinical trial evaluating aH5N1c and Placebo for Avian Influenza. Completed, enrolled 3,196 participants across 26 sites.
Detailed Summary
This Phase 3 study evaluates the safety, immunogenicity and lot-to lot consistency of 3 lots of aH5N1c vaccine for pandemic avian influenza, in approximately 2394 healthy adults ≥18 years of age receiving the vaccine and 797 healthy adults receiving placebo. Subjects were randomized in a 3:1 ratio to receive either aH5N1c vaccine or saline placebo. Enrollment was stratified by age: 18 to \<65 years of age and ≥65 years of age, to allow adequate safety assessment of the entire age spectrum.
