Abstract
The present invention provides an avian recombinant herpesvirus modified by the presence of the cDNA encoding, the VP2 of the Delaware Variant E strain of IBDV, a subtype of IBDV serotype 1 strains. The present invention further provides an avian recombinant herpesvirus comprised of the VP2 gene of which the backbone virus is a Marek's disease vaccine strain, such as herpesvirus of turkeys. A poultry vaccine including the avian herpes recombinant virus described in the present invention can induce in chickens protective immunity against a variety of different subtypes of IBDV.
