Abstract: The disclosure provides methods for generating an optimized nucleotide sequence encoding an engineered influenza structural protein and the optimized nucleotide sequences obtained therefrom. The optimized nucleotide sequences can be used in a reverse genetics system to facilitate the rescue of infectious influenza virus containing the engineered structural proteins and/or enhance viral titers. Also provided are methods of preparing an influenza vaccine composition using the optimized nucleotide sequences, as well as methods of inducing an immune response using the influenza vaccine composition.

Abstract: Provided are octavalent influenza vaccine compositions comprising eight mRNA, each mRNA comprising an open reading frame encoding a different influenza antigen. Also provided are lipid nanoparticles (LNPs) for delivering said mRNA.

Abstract: Co-administration (for example, immunogenic cocktail compositions and/or prime boost regimens) of computationally optimized H1N1 influenza hemagglutinin (HA) polypeptides is provided. Coadministration of the optimized H1N1 influenza hemagglutinin (HA) polypeptides facilitates synergistic neutralization of viral infection and provides for improved protective immunity (for example, a broad reactive immune response) to diverse and multiple H1N1 influenza virus strains, including both seasonal and pandemic strains.
