## Major achievement

Research Summary
Chen Hualan presided over the National Avian Influenza Reference Laboratory and systematically carried out the epidemiological monitoring and research work of avian influenza in China, and achieved a series of significant progress and creative research results, and initially clarified the molecular genetics, antigenic variation and pathogenicity of the avian influenza virus. The law of evolution provides a comprehensive scientific basis for the early warning and forecasting of the epidemic, prevention and control strategies, the development and use of diagnostic reagents and vaccines. During the prevention and control of avian influenza, the rapid and accurate diagnosis of a large number of samples from all over the country played a key role in the timely and effective control of the epidemic. It has made a significant contribution to the control of the bird flu epidemic.
Leading the National Avian Influenza Reference Laboratory has made a series of significant progress and creative research results in the epidemiology, diagnostic technology, new vaccine development, molecular evolution and molecular pathogenic mechanism of animal influenza, especially avian influenza, and successfully developed H5 The subtype inactivated avian influenza vaccine and the new "avian influenza and Newcastle disease recombinant dual live vaccine" represent the international advanced level and development trend of the avian influenza vaccine development. After the promotion and application, it has greatly improved the prevention and control of poultry in China and the world. The ability of influenza has very important socio-economic and public health significance.[13]
In April 2013, Chen Hualan and her scientific research team discovered that the new H7N9 influenza virus that causes human infection in China is highly homologous to the H7N9 avian influenza virus that existed in the live poultry market during the same period. It is the first internationally from the perspective of etiology. The source of the new H7N9 influenza virus was revealed, which provided an important basis for the scientific prevention and control of H7N9 avian influenza in China. In May, they discovered that the H5N1 virus could indeed reassort with the human influenza virus to obtain the ability to transmit efficiently through the air between mammals, thus having the potential to cause a human pandemic, revealing the H5N1 virus from a new perspective. A real threat to global public health. In July, she and researchers found that the H7N9 virus is not pathogenic to poultry, but after the virus invades the human body and mutates, its pathogenicity and horizontal transmission ability to mammals are significantly enhanced, thus revealing the existence of H7N9 virus. The risk of a pandemic among adults. These results have been published in the English version of "Science Bulletin" and "Science (SCIENCE)" magazine.[13]
On November 20, 2019, the Chinese Academy of Agricultural Sciences released 10 basic scientific research results that can fully represent the frontier research level of my country's agricultural science and technology in 2018 and have made major breakthroughs, including: the rapid development of the H7N9 highly pathogenic avian influenza virus Evolution and its successful prevention and control. The research was led by the team of Academician Chen Hualan from the Harbin Veterinary Research Institute of the Chinese Academy of Agricultural Sciences. Through large-scale monitoring of poultry avian influenza viruses, the H7N9 highly pathogenic avian influenza viruses were systematically studied and successfully developed H5 and H7 bivalents. The avian influenza inactivated vaccine, monitoring results showed that the vaccine effectively blocked the H7N9 virus from spreading in poultry, and it also achieved "immediate results" in blocking human infection with the H7N9 virus.
