Recently, the World Health Organization said that six vaccines have entered the third phase of clinical trials, including three from China. This news seems to show the people of China their progress. To study virus vaccine, the first condition is to have advanced medical equipment, and the most important thing is the scientific and technological level of a country. Six vaccines entered the third phase of the experiment, and three vaccines came from China, which showed the advanced technology of China and the great strength of China. However, why do you want to comment like this? 1. It is difficult to develop a vaccine. With the progress of science and technology, people have more and more ways to fight diseases, among which developing vaccines is a very effective method. However, it is not easy to develop a vaccine. The first step is to extract the virus. This stage is very dangerous. If you are inadvertently infected during the extraction process, it is likely to spread the virus to the society. The next step is to cultivate the virus, which requires high technology. It is necessary to cultivate the virus in a sterile environment and let it reproduce. Finally, it can be used to treat diseases through attenuated and clinical trials. Although there are only a few simple steps, each step tests people's lives and the scientific and technological level of a country. Therefore, China can break through these difficulties, which shows China's great power style.
China thinks more about the world. COVID-19 first broke out in China. Thanks to China's efforts, China has effectively controlled the epidemic. But the epidemic has spread to other countries, causing the world to be invaded by viruses. China has invested a lot of money in the research and development of this vaccine, with the main goal of bringing a safe living environment to the world, not only to China, but also to the world. Only when the epidemic situation is controlled can the economy of each country develop normally. Therefore, China's efforts to develop vaccines have demonstrated China's great power style.
China's scientific and technological level has been significantly improved, and its own progress has promoted the development of the world and enhanced China's image as a great country.
