Successful development of inactivated vaccine against H7 subtype recombinant avian influenza virus

Recently, the reporter learned from the Ministry of Agriculture that the National Avian Influenza reference Laboratory has successfully developed an inactivated recombinant avian influenza virus vaccine (H7 subtype, H7N9/PR8 strain) and passed the evaluation of new veterinary drugs as an emergency technical reserve.

In order to further do a good job in H7N9 influenza epidemic response, timely detection and elimination of poultry H7N9 influenza virus, and ensure the quality and safety of animal products and public health safety, the Ministry of Agriculture formulated and implemented the "National Poultry H7N9 Influenza Elimination Plan". While implementing the elimination plan, the Ministry of Agriculture has actively organized the National Avian Influenza reference Laboratory to develop a H7N9 bird flu vaccine in case of urgent need. Thanks to the painstaking efforts of researchers, an inactivated recombinant avian influenza virus vaccine (H7 subtype, H7N9/PR8 strain) was successfully developed. The test results show that the vaccine is safe, the immune effect is good, can provide effective protection against H7N9 avian influenza virus attack, can prevent virus replication and excretion, and is of great significance in effectively blocking virus transmission and reducing the risk of highly pathogenic mutation of the virus. Once epidemic prevention and control needs, the vaccine can be used to immunize poultry immediately to ensure that H7N9 avian influenza can be prevented and controlled.
