Comparative Safety and Immunogenicity of 1.0 µg Intramuscular (i.m.) and 2.0 µg Subcutaneous (s.c.) Dosing With VAX102 (M2e-flagellin) Universal Influenza Vaccine in Healthy Adults

1. To assess the safety, reactogenicity, tolerability, and adverse events (AEs) of the VAX102 vaccine in a two dose regimen (Day 0 and Day 28) at the 1.0 µg dose level delivered i.m., or the 2.0 µg dose level delivered s.c. in a healthy adult population. 2. To assess the immunogenicity (anti-M2e serum antibody concentration) of the VAX102 vaccine in a two dose regimen (Day 0 and Day 28) at the 1.0 µg dose level delivered i.m., or the 2.0 µg dose level delivered s.c. as measured by an enzyme-linked immunosorbent assay (ELISA) in a healthy adult population.
