Academician Chen Hualan: Realizing the breakthrough of animal vaccine research and development from "0" to "1"

"The internationally advanced highly pathogenic avian influenza vaccine created in the international and advanced diseases has more than 300 billion feathers at home and abroad. At the Heilongjiang · 2022 Biological Economy Science and Technology Innovation and Development Forum, Chen Hualan, an academician of the Chinese Academy of Sciences and director of the National Avian Influenza Reference Laboratory of the Harbin Veterinary Institute of the Chinese Academy of Agricultural Sciences, shared the achievements and achievements and achievements and achievements of biotechnology in the field of major animal epidemic prevention and control fields and experience.

"In the past 20 years, the National Avian flu reference laboratory has carried out a full -chain research on the discovery, cognition, prevention and control 'of bird flu viruses'' 'discovery, cognition, prevention and control', and obtained 4 new veterinary drug registration certificates in four countries. These are the real" The breakthrough of '1'. "Academician Chen Hualan introduced.

The cunning virus is constantly mutating. To this end, Academician Chen Hualan led the team to systematically monitor the avian influenza virus, systematically studied the biological characteristics such as evolution, mutation, and communication, and obtained a series of original discovery. The new type of H5/H7 developed by the team has an active vaccine of the two -valent vaccine, which effectively controls the popularity of the H7N9 virus in poultry, and has successfully blocked the human infection with the H7N9 virus. "Disease" is a model of "human illness and beast defense".

Since January 2020, the new H5 virus has caused the outlook of bird flu in more than 20 countries around the world, causing hundreds of millions of poultry to be destroyed. In my country, because of the high pathogenic avian influenza vaccine, China is immune and poultry.

Coincidentally, Harbon has also achieved a breakthrough from "0" to "1" in the creation of African swine fever vaccines.

African swine fever is the number one killer in the world's pig industry. African swine fever vaccines studied in many countries cannot provide effective protection. In 2018, African swine fever was introduced to my country, and the Harbin Beast Research National African Swine Favorite Laboratory was scientific and technological. It created the first safe and effective African swine fever vaccine on the technical level in early 2020. According to the requirements of veterinary drug review, it has been completed. The clinical trial of 15,000 pigs has good safety and effectiveness for home pigs.

Why can you achieve the success of the vaccine development so quickly? Academician Chen Hualan shared the experience of Ha Beast Research, because of the investment accumulation of platforms and talent team construction, including P3, P4 high -level biological safety laboratory platform support, high -standard SPF pig biomass materials guarantee, mature vaccine industrialization trials The base, the cooperative innovation mechanism of research, production, and use, high -quality, responsible scientific research talent team. At the same time, the research has also received strong support from the Agricultural and Rural Ministry of the Ministry of Agriculture and Rural Animal Husbandry and Veterinary Affairs, the national and provincial animal CDCs, the high -level biological safety laboratory of the national animal epidemic prevention and control, and the relevant departments of Heilongjiang Province.
