Provided herein are methods for treating, reducing or preventing influenza A virus infection in a patient, as well as compositions and articles of manufacture for treating, reducing or preventing influenza A virus infection in a patient.

The present invention provides an anti-influenza virus agent that targets biomolecules of host cells including human cells and a method of screening a candidate molecule for the anti-influenza virus agent. That is, the present invention is an anti-influenza virus agent that has an effect of suppressing expression or a function of a gene that encodes a protein having an effect of suppressing incorporation of an influenza virus vRNA or an NP protein into influenza virus-like particles in host cells and the gene is at least one selected from the group including JAK1 gene and the like.

Disclosed herein are multivalent vaccine or immunogenic compositions comprising one or more recombinant influenza virus hemagglutinin (HA), one or more recombinant influenza virus neuraminidase (NA), and an optional adjuvant. Also disclosed are methods of using the vaccine or immunogenic composition.

Material complexes that capture biologicals and methods of synthesizing and using such complexes composed of fluid-insoluble material and a receptor are provided herewith. The fluid-insoluble material has reactive functionality on its surface, including hydroxyl, amino, mercapto or epoxy functionality material. The material can be agarose, sand, textile, or any combination thereof. The receptor is selected from the group consisting of mono- and poly-saccharides, heparin, or any combination thereof. Also provided are methods whereby releasing the captured biologicals is controllable.

The present inventors discovered that antibodies having weaker antigen-binding activity at the early endosomal pH in comparison with that at the pH of plasma are capable of binding to multiple antigen molecules with a single antibody molecule, have long half-lives in plasma, and have improved durations of time in which they can bind to antigen.

Influenza vaccines are administered using solid biodegradable microneedles. The microneedles are fabricated from the influenza vaccine in combination with solid excipient(s) and, after penetrating the skin, they dissolve in situ and release the vaccine to the immune system. The influenza vaccine is (i) a purified influenza virus surface antigen vaccine, rather than a live vaccine or a whole-virus or split inactivated vaccine (ii) an influenza vaccine prepared from viruses grown in cell culture, not eggs, (iii) a monovalent influenza vaccine e.g. for immunising against a pandemic strain, (iv) a bivalent vaccine, (v) a tetravalent or >4-valent vaccine, (vi) a mercury-free vaccine, or (vii) a gelatin-free vaccine.

Compositions and methods for detecting presence of an emerging influenza virus in a sample, such as a biological sample obtained from a subject or an environmental sample, are disclosed. In some embodiments, the compositions and methods can be used to quickly identify particular subtypes of influenza virus (such as a pandemic and/or emerging influenza virus subtype). Probes and primers are provided herein that permit the rapid detection and/or discrimination of pandemic influenza virus subtype nucleic acids in a sample. Devices (such as arrays) and kits for detection and/or discrimination of influenza virus subtype nucleic acids are also provided.

This disclosure provides attenuated swine influenza strains, particularly those produced via a reverse genetics approach, compositions comprising same, and methods of production and use thereof.

The present invention relates to novel peptidomimetic compounds that are capable of binding to and/or neutralizing influenza viruses, in particular influenza A viruses of phylogenetic group 1, and to pharmaceutical compositions comprising such compounds. The invention also relates to the use of the peptidomimetic compounds in the diagnosis, prophylaxis and/or treatment of influenza virus infections.
