CCTV News:The State Council Information Office today (June 7) released the white paper "China Action against COVID-19 Epidemic" and held a press conference to introduce the white paper.
Wang Zhigang, Minister of Science and Technology, in response to a question from a reporter in Reuters, pointed out that since the outbreak of the epidemic, all countries have paid close attention to the vaccine problem. The white paper also includes the related contents of scientific and technological support against epidemic, such as how to combine scientific research such as drugs and vaccines with clinical first-line treatment practice, and how to use big data and artificial intelligence to support against epidemic. As far as the vaccine itself is concerned, judging from the understanding of human response to the epidemic in history, the vaccine is still the fundamental strategy for us to defeat COVID-19 virus at present. All countries put the development of vaccines in a very important position in the fight against COVID-19. But at the same time, we should also see that vaccine development is a very rigorous and complicated scientific activity, which is very difficult and has a long cycle. At the same time, because it is a scientific research, it also has great challenges and uncertainties. Some scientists compare the rigor of vaccine development to an accurately rehearsed dance, rather than an impromptu performance that can be displayed after the curtain is lifted. Therefore, safety, effectiveness and accessibility must be placed in a very important position in vaccine development. Vaccine development has played an important role in human history, but some vaccines have also gone through some detours.
疫苗成功的标志，最重要的是坚持安全、有效和可及。从科学研究上讲，疫苗研制一般要经过病毒分离、实验室疫苗构建、细胞试验、动物试验、临床研究，然后才是规模化生产，最后要经药监部门注册批准才能上市应用。我国按照五条技术路线部署疫苗研发，包括灭活疫苗、腺病毒载体疫苗、重组蛋白疫苗、减毒流感病毒载体疫苗以及核酸疫苗。在疫苗研制过程中和今后的临床试验应用，这两个方面都要加强国际合作。前期我们在整个疫苗研制过程中，都开展了很多国际合作，中国的科学家和其他国家的科学家，都是为了应对疫情，都希望在卫生健康方面为人类命运共同体作出贡献。下一步，中国疫苗如果完成了研制和临床试验后，可以达到应用的时候，我们会认真落实国家主席习近平在第73届WHO大会上的承诺，把它作为公共产品向全球提供。
