  • Publication number: 20090010963
    Abstract: The present invention relates to recombinant raccoon poxvirus vectors that express the rabies virus glycoprotein gene at the hemagglutinin (ha) locus of the poxvirus genome or express the glycoprotein gene of the same or different rabies strains at the thymidine kinase (tk) and the hemagglutinin (ha) loci of the poxvirus genome, and their use as adjuvant-free vaccines. The raccoon poxvirus vector comprises the nucleic acid molecules encoding the glycoprotein of a Challenge Virus Standard rabies strain inserted and expressed at the tk locus of the poxvirus genome and of a Pasteur-Paris rabies strain inserted and expressed at the ha locus of the poxvirus genome. The vaccine may optionally contain a mixture of additional feline and canine antigens for immunization of animals. Also disclosed are methods for inducing an immune response to rabies in a mammal by administering to the mammal an effective immunizing amount of the vaccine of the invention.

  • Publication number: 20080299149
    Abstract: The present invention relates to new recombinant raccoon poxvirus vectors comprising two or more exogenous nucleic acid molecules, each encoding at least one feline protein, wherein at least two of the nucleic acid molecules are inserted into the hemagglutinin (ha) locus or the thymidine kinase (tk) locus, or at least one of the nucleic acid molecules is inserted into each of the hemagglutinin and thymidine kinase loci. Described herein are monovalent and polyvalent recombinant feline vaccines that encompass an immunologically effective amount of the recombinant raccoon poxvirus vectors and, optionally, a suitable carrier or diluent. The vaccine of this invention optionally includes additional feline antigens to provide broad spectrum protection to cats against a variety of feline pathogens. The invention further concerns the method for inducing a protective immune response to the feline pathogens in a cat by administering the recombinant vaccines.
