Recombinant Hvt Vectors Expressing Multiple Antigens Of Avian Pathogens, And Vaccines Comprising Them

Patent No. EP3554536 (titled "Recombinant Hvt Vectors Expressing Multiple Antigens Of Avian Pathogens, And Vaccines Comprising Them") was filed by Hring on Dec 13, 2017. The application was issued on Oct 26, 2022.

Patent Summary

Multivalent recombinant viral vectors for simultaneously delivering multiple antigens against different avian pathogens in a single vaccine. The vectors are based on the herpesvirus of turkeys (HVT) and contain multiple heterologous genes encoding antigens from pathogens like Newcastle disease virus (NDV), infectious bursal disease virus (IBDV), infectious laryngotracheitis virus (ILTV). The antigens are linked by elements like IRES or P2A to facilitate co-expression. This allows efficient expression of multiple antigens from a single vector without instability issues.
