Epitope-optimized vaccine elicits enduring immunity against swine influenza A virus.

ABSTRACT: Swine Influenza A Virus (IAV-S) poses a significant burden to both the pork industry and public health. Current vaccines against IAV-S are infrequently updated and induce strain-specific immunity. Computational platforms have recently emerged as a promising strategy to develop new-age vaccines. Here, we describe the Epigraph, a computationally derived and epitope optimized set of vaccine immunogens. When compared to wildtype immunogens (WT) and a commercial comparator (FluSure XP®), pigs immunized with Epigraph demonstrate significantly improved breadth and magnitude of antibody responses. Further, pigs immunized with Epigraph show more robust and a wider breadth of cross-reactive cell-mediated immune responses than pigs immunized with WT immunogens. In an experimental infection model, Epi
