About Inovio's Universal Influenza DNA Vaccine ProgramInovio aims to leverage the greater breadth of immune responses achievable using its SynCon® vaccine design to revolutionize the flu vaccine market. We are advancing the development of a universal seasonal flu vaccine to protect against H1N1, H3N2, and Type B influenza strains, the subtypes comprising today's FDA-approved seasonal vaccines. In addition to the ongoing H1N1 study in elderly subjects (65+ years), for which we reported positive interim data in December, the company is completing immunogenicity testing across multiple strains in animal models of its vaccine constructs for A/H3N2 and Type B influenza. We are also advancing development initiatives focused on the pandemic influenza subtypes H5N1 and H7N9. Our goal is to access the pandemic stockpiling market, which is dominated by government buyers.
