Abstract: A nucleic acid vaccine composition comprising one or more of a plasmid-based nucleic acid vaccine and immunotherapy, as well as a lipid formulation, is provided. In addition, the present invention provides a method of enhancing the potency of plasmid-based DNA vaccines and immunotherapies, by formulating a vaccine and/or immunotherapy in a lipid formulation, which is stable when refrigerated or stored frozen, is then delivered to a vaccinee by either needle/syringe, jet injection, or microneedles. The lipid formulation of the present invention comprises one or more lipid excipients selected from 1,2-Distearoyl-sn-glycero-3-phosphocholine, Cholest-5-en-3?-ol, 1,2-Dimyristoyl-rac-glycero-3-methylpolyoxyethlene, and or more symmetric ionizable cationic lipids. The present invention increases vaccine potency dramatically.

Abstract: The current disclosure provides a severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike-based DNA vaccine capable of eliciting immune response to a SARS-CoV-2 in a human subject upon administration. Also provided is a method of eliciting an immune response to a SARS-CoV-2 in a human subject by administering the SARS-CoV-2 spike-based DNA vaccine, for example, intramuscularly using a jet injector.

Abstract: Disclosed herein are methods of making attenuated Arenaviruses, compositions comprising the attenuated Arenaviruses, and methods of using the attenuated Arenaviruses. As disclosed herein, the attenuated Arenaviruses have a deletion of at least a portion of the intergenic region (IGR) of one or both genome segments.

Abstract: The invention described here encompasses DNA and protein vaccines against poxviruses, and relevant immunogenic compositions, comprising at a minimum a nucleic acid encoding a modified full-length poxvirus L1R gene or its ortholog. The L1R gene is modified so that an endoplasmic reticulum-targeting sequence is operably linked on the 5? end. Preferably the nucleic acid sequences for other poxviruses antigens are also included, such as A33R, B5R and/or A27L. These vaccines and compositions provide improved neutralizing antibody response elicited by molecular poxvirus vaccines, over known vaccines using unmodified L1R.

Abstract: The invention described here entails a protein vaccine against poxviruses which contains at least two purified recombinant monkeypox virus proteins or peptides. The proteins or peptides are encoded by the open reading frames of the monkeypox ortholog genes M1R, A35R, A29L B6R, and orthologs of these proteins or peptides having 90% identity. The invention also entails a vaccine protocol against poxvirus whereby a vaccine is vaccinated with a first vaccine made up of a nucleic acid vaccine of three or more poxvirus virus genes, and subsequently vaccinated with at least one other booster vaccine made up of two or more poxvirus virus proteins.

Abstract: In this application is described a protective DNA vaccines against infection with HFRS- and HPS-associated hantaviruses. The vaccines were constructed by subcloning cDNA representing the medium (M) (encoding the G1 and G2 glycoproteins) into the DNA expression vector pWRG7077. Animals vaccinated with the M construct developed a neutralizing antibody response. Passive transfer experiments show that serum from vaccinated animals, when injected on days 4 or 5 after challenge, protected animals from lethal disease.
