The present invention relates to Equine Herpes Virus (EHV) vectors comprising at least one exogenous antigen encoding sequence relating to a pathogen infecting food producing animals, wherein said exogenous antigen encoding sequence is inserted into an insertion site, preferably ORF70, and said exogenous antigen encoding sequence is operably linked to a promoter sequence, preferably the promoter sequence comprising 4pgG600 (SEQ ID NO:1) or 4pMCP600 (SEQ ID NO:2) or the complementary nucleotide sequences thereof or a functional fragment or a functional derivative thereof or the complementary nucleotide sequences thereof. Furthermore, the present invention relates to methods for immunizing a food producing animal comprising administering to such food producing animal an immunogenic composition comprising embodiments of the present invention. Moreover, the present invention relates to methods for the treatment or prophylaxis of clinical signs caused by swine influenza virus in a food producing animal.

Embodiments of the instantly claimed inventions include, but are not limited to, chimeric viral constructs, non-human primate models, in vivo screening systems for antiviral agents, gene therapy delivery systems, and methods of making and using the same. In some embodiments, chimeric viral constructs include a non-human primate infecting virus nucleic acid sequence and a exclusively human pathogenic virus nucleic acid sequence for use in creating a non-human primate model and uses thereof. In other embodiments, systems for testing antiviral agents are disclosed. In other embodiments, gene therapy delivery systems disclosed herein can be used to deliver a vector containing or associated with an agent to a human subject for treating conditions of the skin and neuronal ganglia in the subject.

The invention relates to a Quadruple Gene Deleted Mutant Bovine Herpesvirus Type 1 (BHV-1 QMV) engineered to express protective antigens derived from viruses associated with infection in livestock. The recombinant vector includes a deletion of a cytoplasmic tail of envelope glycoprotein gE (gE-CT), a truncation of glycoprotein gG, a deletion of envelope protein UL49.5 amino acid residues 30-32, and a deletion of UL49.5 cytoplasmic tail amino acid residues 80-96. The truncation of glycoprotein gG comprises a deletion of amino-terminal amino acid residues 1-67. The recombinant vector can include at least two heterologous antigens inserted therein. Included are methods for creating recombinant vectors, mutant viruses, and vaccines for preventing or reducing symptoms associated with viral infection in livestock, in particular bovine respiratory viral infection

The present invention relates to the field of (vector) vaccines, and especially to novel EHV's having an inactivation of UL18 and/or UL8. The present invention further concerns related expression cassettes and vectors, which are suitable to express genes of interest, especially antigen encoding sequences. The viral vectors of the present invention are useful for producing an immunogenic composition or vaccine.

The disclosure provides recombinant herpes virus with diminished latency. In embodiments, the recombinant herpes virus comprises a latency gene or transcript linked to an altered or heterologous promoter. The disclosure also provides compositions and methods for inducing immunity in animals using the recombinant herpes viruses.
