The disclosure relates to respiratory virus ribonucleic acid (RNA) vaccines and combination vaccines, as well as methods of using the vaccines and compositions comprising the vaccines.

A method for producing a clone of an immortalised human B memory lymphocyte, comprising the step of transforming human B memory lymphocytes using Epstein Barr virus (EBV) in the presence of a polyclonal B cell activator. The method is particularly useful in a method for producing a clone of an immortalised human B memory lymphocyte capable of producing a human monoclonal antibody with a desired antigen specificity, comprising the steps of: (i) selecting and isolating a human memory B lymphocyte subpopulation; (ii) transforming the subpopulation with Epstein Barr virus (EBV) in the presence of a polyclonal B cell activator; (iii) screening the culture supernatant for antigen specificity; and (iv) isolating an immortalised human B memory lymphocyte clone capable of producing a human monoclonal antibody having the desired antigen specificity.

Among other things, the present disclosure provides agents that can bind to viruses such as SARS-CoV-2 and/or cells infected thereby. In some embodiments, the present disclosure provides methods for preventing and/or treating conditions, disorders or diseases associated with SARS-CoV-2 infection. In some embodiments, the present disclosure provides methods for preventing and/or treating COVID-19.

The present invention provides for cross-neutralizing SARS-COV2 antibodies. The antibodies can be used to treat SARS-CoV2 and variants thereof.

Provided herein are antibodies and antibody fragments that bind to the S2 domains of SARS-CoV-2, SARS-CoV, and MERS-CoV spike proteins. Methods of using these antibodies in in vitro methods are provided. Methods of using these antibodies in vivo to treat or prevent SARS-CoV-2 infections are also provided.

The present invention relates to compositions and methods for the treatment of immunodeficiency (e.g., primary immunodeficiency disease). In particular, the invention provides human plasma immunoglobulin compositions containing select antibody titers specific for a plurality of respiratory pathogens, methods of identifying human donors and donor samples for use in the compositions, methods of manufacturing the compositions, and methods of utilizing the compositions (e.g., for prophylactic administration and/or therapeutic treatment (e.g., passive immunization (e.g., immune-prophylaxis))).

The disclosure relates to respiratory virus ribonucleic acid (RNA) vaccines and combination vaccines, as well as methods of using the vaccines and compositions comprising the vaccines.

Methods of inducing an immune response in a subject to the Middle East respiratory syndrome coronavirus (MERS-CoV) are provided. In several embodiments, the immune response is a protective immune response that inhibits or prevents MERS-CoV infection in the subject. Recombinant MERS-CoV polypeptides and nucleic acid molecules encoding same are also provided. Additionally, neutralizing antibodies that specifically bind to MERS-CoV S protein and antigen binding fragments thereof are disclosed. The antibodies and antigen binding fragments are useful, for example, in methods of detecting MERS-CoV S protein in a sample or in a subject, as well as methods of preventing and treating a MERS-CoV infection in a subject.

The present invention relates to a vaccine for protecting a pig against diseases associated with porcine epidemic diarrhea virus. The vaccine commonly includes inactivated/killed PEDV (e.g., chemically inactivated PED virus), and/or recombinant PEDV antigen and an adjuvant. Methods for protecting pigs against diseases associated with PEDV and methods of producing the porcine epidemic diarrhea virus vaccine are also provided.

The disclosure relates to ribonucleic acid (RNA) vaccines and combination vaccines, as well as methods of using the vaccines and compositions comprising the vaccines.
