Abstract: Formulations and preparations having immune memory enhanced properties are disclosed that provide for enhancing immune response against a tumor growth, cancer, infectious agent, bacteria, virus or other infectious or non-infectious agent. The vaccine formulation includes an immune memory invoking component, such as an antigen of an infectious agent, virus (e.g., Rabies), bacteria, prion, neo-antigen or other moiety antigen, and a targeted antigen (e.g., a harvested tumor tissue (B-cell, T-cell, epitopes)). The vaccine formulation/preparations may comprise a target infectious agent protein/peptide component (such as a SARS-Cov-2 spike protein epitope) mixed with, or fused to (or otherwise conjugated) an immune-memory associated viral antigen (such as Rabies, polio, or other peptide/protein antigen or peptide or fragment thereof).

Abstract: The present invention provides an isolated antibody capable of binding to the receptor-binding domain of the spike protein of the severe acute respiratory syndrome-associated coronavirus (SARS-CoV) so as to competitively inhibit the binding of the SARS-CoV to host cells. These mAbs or substances can be used: 1) as passive-immunizing agents for prevention of SARS-CoV infection; 2) as biological reagents for diagnosis of SARS-CoV infection; 3) as immunotherapeutics for early treatment of SARS-CoV infection; and 4) as probes for studying the immunogenicity, antigenicity, structure, and function of the SARS-CoV S protein.
Abstract: The present disclosure relates in part to methods of treating, preventing, and/or ameliorating SARS-CoV-2 infection and/or related inflammatory syndromes by administration of a Maackia amurensis seed lectin (MASL). MASL has a strong affinity for sialic acid modified proteins and may be used as an antiviral agent. This lectin targets the ACE2 receptor, decreases ACE2 expression and glycosylation, suppresses binding of the SARS-CoV-2 spike protein, and decreases expression of inflammatory mediators by oral epithelial cells that cause ARDS in COVID-19 patients.
Abstract: Methods of preventing or treating infection by a SARS-CoV-related betacoronavirus are described. The methods include administering to a patient at risk of being infected by a SARS-CoV-related betacoronavirus or suffering from SARS-CoV-related betacoronavirus-related illness a small molecule drug and/or an antibody that binds to the ACE2-SARS interaction domain of either ACE2 or SARS-CoV-2 spike protein. Also described are vaccines comprising S-protein polypeptides corresponding to the ACE-2 interaction domain.

Abstract: Timely development of vaccines and antiviral drugs is critical to control the COVID-19 pandemic. Current methods for quantifying vaccine-induced neutralizing antibodies involve the use of pseudoviruses, such as the SARS-CoV-2 spike protein (S) pseudotyped lentivirus. However, these pseudoviruses contain structural proteins foreign to SARS-CoV-2, and require days to infect and express reporter genes. Here, the present application discloses composition and methodology for making and using a new hybrid alphavirus-SARS-CoV-2 (Ha-CoV-2) particle for rapid and accurate quantification of neutralization antibodies and viral variants.
Abstract: There is provided a method of identifying/characterising coronavirus infection in a human subject. In a specific embodiment the method comprising contacting a serum sample from the subject with an isolated host cell expressing a nucleotide that encodes for a codon optimised gene for SARS-CoV-2 spike protein (S protein); and detecting a binding of an antibody or an antigen-binding fragment thereof to said host cell using a flow cytometry and a labelled anti-human secondary antibody. Also disclosed is a method of identifying a subject having immunity for coronavirus, especially SARS-CoV-2 wherein a sample from a subject is incubated with said cell and is detected using the flow cytometry and the labelled anti-human secondary antibody. Nucleic acid encoding a SARS-CoV-2 S protein, viral vectors and host cells thereof are also disclosed.
