Abstract: The invention provides flavivirus vaccines and methods of making and using these vaccines.

Abstract: Described herein are dengue virus E-glycoprotein polypeptides containing mutations that eliminate immunodominant cross-reactive epitopes associated with immune enhancement. The disclosed dengue virus E-glycoproteins optionally further include mutations that introduce a strong CD4 T cell epitope. The disclosed E-glycoprotein polypeptides, or nucleic acid molecules encoding the polypeptides, can be used, for example, in monovalent or tetravalent vaccines against dengue virus.

Abstract: The present invention addresses a need for improved treatments for Filovirus infections.

Abstract: The present invention relates to a method for prevention and/or reduction of aggregation of viral components.

Abstract: Disclosed are compositions and methods comprising vectors and a reverse genetics competent unit comprising one or more recombinant influenza viruses. Recombinant influenza viruses comprising swine RNA polymerase I promoter are disclosed. Constructs comprising swine RNA polymerase I promoter nucleic acid sequences are also provided. Methods of inducing protecting immunity with the recombinant influenza viruses are disclosed. In certain embodiments, the reverse genetics competent unit comprises pathogenic units necessary for producing pathogens de novo from a nucleotide-based vector for influenza virus in swine.

Abstract: The present invention relates to a method for obtaining an untransformed avian cell line enabling in vitro avian virus replication. Said method includes the following steps: a) culturing avian embryonic stem cells in the presence of a stroma for at least 3 days; b) culturing for at least 2 days in a medium having a low serum concentration; c) culturing for at least 2 days in a medium having a low serum concentration containing 1 to 10 mM of hexamethyleme bisacetamide (HMBA); d) culturing for at least 10 days in a medium having a low serum concentration; and e) culturing or freezing an avian cell line enabling avian virus replication. The invention also relates to the resulting cell line and to the use thereof in vaccine preparations.

Abstract: Embodiments of the present invention report compositions and methods for vaccinating a subject against dengue viruses. In some embodiments, vaccine compositions may be administered by intradermal introduction. In certain embodiments, intradermal introduction in a subject of a vaccine against dengue virus may include one or more intradermal boosts after initial vaccination. Other embodiments include intradermal injection of a vaccine composition against dengue virus wherein the composition provides protection against two or more of DEN-1, DEN-2, DEN-3 and DEN-4.

Abstract: The present invention provides monoclonal antibodies that are specific for the Dengue non-structural glycoprotein NS1 in monomeric and/or oligomeric (primarily dimeric) form, together with methods, including ELISA and lateral flow assays, that employ the disclosed antibodies for the early detection of Dengue virus infection. Diagnostic kits for the detection of Dengue infection are also provided, such kits including the disclosed monoclonal and/or polyclonal antibodies.

Abstract: The present invention encompasses novel antibodies and fragments thereof which immunospecifically bind to one or more RSV antigens and compositions comprising said antibodies and antibody fragments. The present invention encompasses methods preventing respiratory syncytial virus (RSV) infection in a human, comprising administering to said human a prophylactically effective amount of one or more antibodies or fragments thereof that immunospecifically bind to one or more RSV antigens, wherein a certain serum titer of said antibodies or antibody fragments is achieved in said human subject. The present invention also encompasses methods for treating or ameliorating symptoms associated with a RSV infection in a human, comprising administering to said human a therapeutically effective amount of one or more antibodies or fragments thereof that immunospecifically bind to one or more RSV antigens, wherein a certain serum titer of said antibodies or antibody fragments is achieved in said human subject.
