Patent ID: 6911206

Claim:
A fusion protein for producing an immune response in a vertebrate, which fusion protein comprises: (a) a first proteinaceous portion comprising a peptide sequence of the gonadotropin releasing hormone (GnRH) peptide as set forth in SEQ ID NO: 13 connected to (b) a second proteinaceous portion comprising a polypeptide sequence of the Bovine Herpes Virus Type-1 (BHV-1) gD protein as set forth in SEQ ID NO: 29; wherein the activity of said GnRH peptide is to be inhibited within the vertebrate, and which proteinaceous portion by itself is incapable of eliciting an effective immunoinhibitory response in said vertebrate and when the vertebrate is vaccinated with an effective amount of said fusion protein, the vertebrate recognizes said first proteinaceous portion (a) and induces an immune response capable of inhibiting the activity of said GnRH peptide within the vertebrate.
