MULTIVALENT HVT VECTOR VACCINE
20230031097 · 2023-02-02 · ·

The present invention describes a recombinant herpesvirus of turkeys (rHVT) that can be used as a vector vaccine for poultry against infection and disease from multiple poultry pathogens. Specifically the rHVT expresses an infectious bursal disease virus (IBDV) viral protein 2 (VP2) gene and a Newcastle disease virus (NDV) fusion (F) protein gene from a first and a second expression cassette inserted in the unique small (Us) region, and expresses an avian influenza vims (AIV) haemagglutinin (HA) gene from a third expression cassette inserted in the unique long (UL) region of the genome of said rHVT either between the UL40 and UL41 genes, or between the UL44 and UL45 genes. This rHVT can be used to vaccinate poultry against MDV, IBDV, NDV and AIV.
