Xinhua News Agency successfully developed the human bird flu vaccine (photographed on November 14). Xinhua News Agency issued Xinhuanet Beijing on November 14th (reporter Zhang Xiaosong and Zou Shengwen). The “human bird flu vaccine development†project was approved by the Ministry of Science and Technology on the afternoon of the 14th. This indicates that China has completed the preclinical research on human bird flu vaccines, indicating that China's scientific research in this area has been synchronized with the world. At present, the vaccine development units Beijing Kexing Biological Products Co., Ltd. and the Chinese Center for Disease Control and Prevention have submitted applications for clinical research to the State Food and Drug Administration. According to Yu Yongxin, member of the project acceptance expert group, highly pathogenic avian influenza is prone to variation and may cause a human influenza pandemic. In response to the flu pandemic caused by the mutation of the bird flu virus, Chinese scientists have conducted a prototype vaccine-human bird flu vaccine research. After more than one year of research, pre-clinical studies have been completed on the human bird flu vaccine project. Scientists have established seed banks for vaccine production using virus species constructed using reverse genetic techniques. They have studied virus amplification capacity, genetic stability, inactivation effects and processes, and have determined the purification process and virus assay methods; Preparation of experimental vaccines, animal experiments showed that the prepared test vaccine has good safety and immunogenicity. Experts pointed out that once the highly pathogenic avian influenza virus breaks through the population's immune defense line, it will evolve into a highly pathogenic influenza virus that will cause a large number of cases of infection and death. Effective vaccination is an effective means to quickly establish a population immune barrier, block the spread of influenza pandemics, and reduce and reduce its harm. Therefore, the “human bird flu vaccine development†project passed the acceptance by experts, which means that China’s human bird flu vaccine research and development has been synchronized with the world, and will provide important technical and material reserves for China’s influenza pandemic prevention. Once the influenza pandemic has broken out, the Chinese government will have the ability to rely on its R&D achievements to control the disease, safeguard the people's health and social stability. It is also understood that before the vaccine is officially put on the market, it is necessary to further prove its safety and effectiveness through clinical research. At present, Beijing Kexing and China CDC have submitted applications for clinical research to the Food and Drug Administration. China National Institute for Pharmaceutical and Biological Products has completed the testing of vaccine species for use in vaccines and issued a test report.
