(staff members work in the subpackaging workshop of novel coronavirus inactivated vaccine of Sinopharm Beijing Institute of biological products.) as of August 27, 31 provinces (autonomous regions and municipalities directly under the central government) and Xinjiang production and Construction Corps in China have reported that more than 3.431 billion doses of novel coronavirus vaccine have been inoculated. In the work of epidemic prevention and control, whether it is the rush to build a shelter hospital or the development of vaccines through multiple technical routes; Science and technology have played a strong supporting role in carrying out large-scale nucleic acid testing, big data tracking and traceability, health code recognition, differentiated prevention and control by regions and levels, and orderly promoting the resumption of work and production. "At present, the main social contradiction in China has been transformed into the contradiction between the people's growing need for a better life and the unbalanced and inadequate development. In order to meet the people's yearning for a better life, we must launch more scientific and technological innovation achievements involving people's livelihood." Since the 18th National Congress of the Communist Party of China, scientific and technological innovation has taken promoting the construction of a modern socialist country and meeting the people's yearning for a better life as its fundamental task, which has effectively supported the improvement of people's livelihood. One scientific and technological innovation after another has effectively served the needs of people's livelihood and continued to "contribute" to the people's better life. Science and technology build a "protective line" for life safety at the beginning of 2020, novel coronavirus suddenly arrived, and the epidemic was fierce. Epidemic prevention and control requires scientific methods and answers. In the face of serious threats to people's lives and health, the national science and technology system has focused on clinical treatment, drug and vaccine research and development to tackle epidemic problems. Novel coronavirus strains were isolated within 7 days, and nucleic acid detection reagents were developed and approved for marketing within 14 days. Wang Zhigang, Minister of science and technology, said that science and technology strongly supported the prevention and control of COVID-19 epidemic, built a "three lines of defense" of vaccines, traditional Chinese medicine, neutralizing antibodies and small molecule drugs, and realized full coverage of five technical routes for vaccine research and development. Seven were approved for use, three were included in the global emergency use list, monoclonal antibody combination drugs became the fourth antibody drug in the world, and 108 detection reagent products were listed. "Just because there are testing reagents, drugs and vaccines, we can form a solid scientific and technological defense line." Wang Zhigang said. The defense line of science and technology to ensure the safety of people's lives and health is constantly strengthening its defense force. During the 12th Five Year Plan period, the state's major science and technology special medical projects have achieved fruitful results in tackling key scientific research problems aimed at the needs of major disease prevention and control. By the end of the 12th Five Year Plan, a total of 90 varieties had obtained new drug certificates. The national science and technology innovation plan for the 13th five year plan further clarifies: improve the technical system to support the improvement of people's livelihood and sustainable development. In terms of population health, during the 13th Five Year Plan period, the central government invested more than 25 billion yuan, involving the creation of new drugs, the modernization of traditional Chinese medicine, and food safety.
