Patent Application Titled "Recombinant Hvt Vectors Expressing Influenza Hemagglutinin And Immunogenic Compositions, And Production And Uses Thereof" Published Online (USPTO 20240252624).

The patent application titled "Recombinant Hvt Vectors Expressing Influenza Hemagglutinin And Immunogenic Compositions, And Production And Uses Thereof" discusses the use of recombinant vaccines to protect avian animals, specifically chickens, from diseases like Newcastle disease, infectious bronchitis, and avian influenza. The inventors propose the use of HVT vectors, derived from the herpesvirus of turkeys, to express antigens from various pathogens and stimulate an immune response. The application also addresses the challenges of developing a broadly protective H5 influenza A vaccine due to the genetic and antigenic diversity of the virus. The patent application provides detailed information on the specific nucleic acid sequences, antigens, and methods used in the invention. [Extracted from the article]
