Abstract
An attenuated, avirulent recombinant vaccine providing challenged protection against channel catfish virus comprises deletion of gene 50. Gene 50 encodes a secreted glycoprotein. Removal of gene 50, or replacement of gene 50 with foreign genetic material, provides a vaccine with which induces virus specific immunity against CCV disease.
