Study of the Safety and Immunogenicity of H1N1 Vaccine
A Phase I Dose-Escalation Study to Investigate the Safety and Immunogenicity of the Fusion Protein Recombinant Influenza A (HAC1) Vaccine Derived From Influenza A/California/04/09 (H1N1) in Healthy Adults
Study Overview
Detailed Description
This is a single center, placebo-controlled, single blinded dose escalation study to preliminarily assess the safety, reactogenicity, and immunogenicity of different HAC1 vaccine formulations. This study will assess a novel HAC1 vaccine, which is plant derived. This vaccine will be compared to Placebo of normal (0.9%) saline, and reference vaccine consisting of an approved monovalent vaccine containing an A/California (H1N1)-like strain.
Subjects will receive 2 intramuscular injections of the experimental vaccine, placebo, or reference vaccine on Study Days 0 and 21
