Improved HVT vector ND-IBD vaccine

摘要

The present invention relates to a new and improved HVT vector ND-IBD vaccine comprising a recombinant HVT comprising an IBDV-derived VP2 gene and an NDV-derived F gene for a target animal. The recombinant HVT can be used in poultry vaccines, which include good viral vector replication, efficient expression of NDV F and IBDV VP2 genes, improved immune protection against ND and IBD, compared to prior art constructs, As well as improved genetic stability.
