Abstract: The present disclosure relates, in part, to anti-influenza antibodies (and antigen binding fragments thereof) and combinations thereof for preventing and treating influenza infection. Presently disclosed combinations provide surprising synergistic effects and can potently prevent, inhibit, or neutralize an influenza infection, such as an influenza A virus (IAV) infection an influenza B virus (IBV) infection, or both.

Abstract: The instant disclosure provides antibodies and antigen-binding fragments thereof that can bind to an influenza virus neuraminidase (NA) and can neutralize an influenza virus infection. Also provided are polynucleotides that encode an antibody, vectors that comprise such polynucleotides, host cells that can express the antibodies, related compositions, and methods of using the herein disclosed compositions to, for example, treat or prevent an influenza infection.

Abstract: The instant disclosure provides antibodies and antigen-binding fragments thereof that can bind to a SARS-CoV-2 antigen and, in certain embodiments, are capable of neutralizing a SARS-CoV-2 infection. In certain embodiments, the presently disclosed antibodies are capable of binding to S proteins of multiple sarbecoviruses and/or neutralizing infection by multiple sarbecoviruses. Also provided are polynucleotides that encode an antibody or antigen-binding fragment, vectors and host cells that comprise a polynucleotide, pharmaceutical compositions, and methods of using the presently disclosed antibodies, antigen-binding fragments, polynucleotides, vectors, host cells, and compositions to treat or diagnose a sarbecovirus infection, such as a SARS-CoV-2 infection.
