In alternative embodiments, provided are methods for treating, ameliorating, decreasing the chances of having any adverse effects from, decreasing the severity of adverse effects from a coronavirus infection, comprising administering to a subject or an individual in need thereof: (a) an anti-viral drug combination capable of killing a causative agent of the infection, or completely or partially inhibiting the ability of the causative agent of the infection to replicate or become infectious or cause pathology in the subject or the individual in need thereof, wherein the anti-viral drug combination comprises: (i) 1R,2S,5S)N-[(1S)-1-cyano-2-[(3S)-2-oxopyrrolidin-3-yl]ethyl]-3-[(2S)-3,3-dimethyl-2-(2,2,2-trifluoroacetamido)butanoyl]-6,6-dimethyl-3-azabicyclo[3.1.0]hexane-2-carboxamide, and (ii) ritonavir; and, (b) an inactivated or attenuated agent of the infection, or a live, viable or infectious causative agent of the infection, or a live causative agent of the infection that is a completely or partially attenuated version of the causative agent, wherein at least one dosage of the anti-viral drug combination is administered to the subject or the individual in need thereof 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13 or 14 or more days before, or on the day of, and/or is administered 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13 or 14 or more days after, a first dose of the inactivated or attenuated agent of the infection.

The present invention generally relates to the field of diagnostic microbiology, and, more particularly, to compositions and methods for detecting and differentiating one or more viruses or other intracellular parasites present in a specimen. The present invention also provides compositions and methods to evaluate the susceptibility of organisms to antimicrobial agents.

The present disclosure relates to a low glycosylated spike protein and a vaccine designed to express the spike protein in vivo. The present disclosure also teaches a method for generating an immune response by utilizing the low glycosylated spike protein, which provides a broader protection across different variants. A method for identifying a glycan-shielded conserved peptide of a glycoprotein is also disclosed.

Antibodies or antigen binding fragments thereof comprising at least one immunogenic peptide inserted into a variable region of the antibody or antigen binding fragment thereof, wherein the insertion comprises removal of antibody or antigen binding fragment sequence are provided. Dual-function antigen binding molecules comprising an antibody or antigen binding fragment of the invention and a second antibody or antigen binding fragment thereof capable of binding an antigen overexpressed on a target cell are provided. Nucleic acid molecules encoding same, pharmaceutical compositions comprising same and methods of treating cancer by administrating same are also provided. Methods of producing antibodies or antigen binding fragments are also provided.

The present disclosure includes compositions and methods for detecting the presence of: a coronavirus or an immune response relevant to a coronavirus infection including T cells responsive to one or more coronavirus peptides or proteins comprising, consisting of, or consisting essentially of: one or more amino acid sequences selected from those sequences set forth in Tables 1 to 10 (SEQ ID NOS: 1 to 3522), or a subsequence, portion, homologue, variant or derivative thereof; a fusion protein; a pool of 2 or more peptides; or a polynucleotide that encodes one or more peptides or proteins, comprising, consisting of, or consisting essentially of one or more amino acid sequences set forth in Tables 1 to 10 (SEQ ID NOS: 1 to 3522), or a subsequence, portion, homologue, variant or derivative thereof. The disclosure further provides vaccines, diagnostics, therapies, and kits, comprising such proteins or peptides.
