  • Avian influenza and fowl adenovirus type 4 bi-combined genetic engineering subunit vaccine and method for preparing the same
    Patent number: 11305006
    Abstract: The disclosure relates to the technical field of veterinary biological products, and discloses an avian influenza and fowl adenovirus type 4 bi-combined genetic engineering subunit vaccine. An antigen in the vaccine is a fusion antigen; the fusion antigen has a) avian influenza virus HA protein; b) fowl adenovirus fiber2 protein; c) a specific linker peptide located between the avian influenza virus HA protein and the fowl adenovirus fiber2 protein; the amino acid sequence of the specific linker peptide is as shown in SEQ ID NO:2. This vaccine contains the fusion antigen which can induce poultries to produce a high-level specific antibody to protect poultries from avian influenza and fowl adenovirus infection. Meanwhile, the disclosure also discloses a method for preparing the vaccine.
