The present invention relates to fluorocarbon vectors for the delivery of influenza antigens to immunoresponsive target cells. It further relates to fluorocarbon vector-influenza antigen constructs and the use of such vectors associated with antigens as vaccines and immunotherapeutics in animals, including humans.

The present invention relates to enveloped RNA viruses. The invention in particular relates to the generation of superior antigens for mounting an immune response by first identifying then mutating the immunosuppressive domains in fusion proteins of enveloped RNA viruses resulting in decreased immunosuppressive properties of viral envelope proteins from the viruses.

The present invention provides compositions and methods for detecting and treating respiratory illness. The methods and compositions described herein comprise at least one probe that may hybridize with a target nucleotide molecule. The target nucleotide molecule may be a part of a virus, which in turn may be present in a subject, such as a human subject.

Disclosed are multivalent vaccine or immunogenic compositions comprising influenza virus hemagglutinin (HA) from standard of care influenza virus strains, or ribonucleic acid molecules encoding the same; and one or more influenza virus HA identified or designed by machine learning, or one or more ribonucleic acid molecules that encode the influenza virus HA identified or designed by machine learning. Also disclosed are methods of using the vaccine or immunogenic compositions.

Attenuated live or replication-deficient chimeric swine influenza virus vaccine, and a platform to develop a multitude of other vaccines in swine and other species. The chimeric influenza virus A comprises a backbone of viral genomic segments derived from influenza A, and expresses a heterologous surface protein (influenza D hemagglutinin esterase fusion protein), and optionally at least one other heterologous protein, such as an antigenic component of a target pathogen.

The present invention provides novel engineered influenza hemagglutinin (HA) proteins, related polynucleotide sequences, and vaccine compositions including nanoparticle compositions. Relative to a wildtype HA protein, the engineered HA proteins are stabilized via substitutions of one or more conserved residues in the HA2 ectodomain with hydrophobic residues. The invention also provides methods of using such vaccine compositions in various therapeutic applications, e.g., for preventing or treating influenza viral infections.
