Abstract: The present invention includes methods of making, compositions, or vaccinations comprising a recombinant vesicular stomatitis vims (rVSV) viral vector that expresses a Nipah Virus protein antigen, wherein the rVSV vector comprises one or more heterologous polynucleotides coding for and expressing a Nipah Virus NiVB G-protein antigen; wherein the NiVB G-protein comprises an amino acid sequence as set forth in SEQ ID NO: 6, or wherein the heterologous polynucleotide encodes a. polypeptide coding for the NiVB G-protein antigen comprising at least 90% sequence identity to an amino acid sequence as set forth in SEQ ID NO: 6, or 90% sequence identity to a nucleic acid sequence as set forth in SEQ ID NO: 2, wherein the composition or vaccine is effective to reduce or prevent a Nipah Virus infection at 3 days.

Abstract: Certain embodiments are directed generally to compositions and methods related to recombinant vesicular stomatitis virus vectors (?GrVSV) encoding Crimean-Congo Hemorrhagic Fever glycoprotein precursor (CCHFV-GPC) and forming a recombinant vesicular stomatitis virus vector encoding Crimean-Congo Hemorrhagic Fever glycoprotein precursor (?GrVSV-CCHFV-GPC).

Abstract: The present invention includes methods of making, and compositions comprising, a uniformly lethal filovirus for outbred small mammals by mutation of the viral genome through serial passages in a small mammal, the method comprising the steps of: obtaining a filovirus strain from a human subject; passing the filovirus strain one or more times by intramuscular injection of one or more filovirus infected tissues into an inbred small mammal until uniform lethality is obtained; passing the filovirus strain in one or more human cell lines; passing the filovirus strain one or more times by intraperitoneal injection of one or more filovirus infected tissues into an outbred small mammal until uniform lethality is obtained; and isolating the uniformly lethal filovirus obtained thereby.
