Empty canine parvovirus capsids having CPV recombinant VP2 and vaccines having such capsids

摘要

The present invention is a method for the production of a subunit vaccine against canine parvovirus (CPV). The method includes the step wherein a recombinant protein VP2 of CPV is obtained by using the replication of a recombinant baculovirus wherein the gene corresponding to VP2 has been previously inserted in cells of a permissive host. The protein VP2 obtained has the capacity of forming empty VP2 capsids with high immunogenicity and can be provided as a vaccine formulation for protecting dogs against CPV infection the recombinant baculovirus AcMNPV. pCPVEx17 expresses the VP2 of CPV in conditions making possible the formulation of pseudo-viral capsids.
