RECOMBINANT HERPES VIRUS OF TURKEY AND BACTERIAL VECTOR VACCINE OF THE VIRUS ORIGIN

摘要

The present invention is concerned with a recombinant Herpesvirus of Turkeys (HVT), containing a heterologous gene incorporated into an insertion-region of the genome of HVT. The invention also relates to a vector vaccine comprising such a recombinant HVT which expresses a heterologous antigenic polypeptide and induces an adequate immune response on infection of an appropriate host animal.
