The present research is being conducted with FluMist®, a commercially available intranasal seasonal influenza vaccine, and the Company anticipates the extension of this clinical research with other promising seasonal influenza vaccines to determine the extent, if any, of cross-reactivity conveyed by co-administration of the selective TLR-3 activator, rintatolimod, which is an experimental immunotherapeutic.
