The global COVID-19 vaccine research and development speed has broken the historical record. The main credit for shortening the research and development time should be that scientific progress has made people know more about the virus. This knowledge is based on the background of big data, so that everyone can find the source of the virus in the first time and find a solution. Medical progress and big data should be the greatest contribution to breaking the historical record of research and development speed.

Times are changing, and so are our perceptions. Science makes us stronger and brings us real convenience and speed. The global COVID-19 vaccine research and development speed has broken the historical record. The shortening of research and development time is the reason for the improvement of medical staff's cognition. The progress of science and technology and enough big data give scientists a good reference, so that medical workers can find the source of the virus as soon as possible, and then prevent and solve problems in a targeted manner. This is why the speed of vaccine research and development has broken the historical record.

First, medical big data has more references, which is the biggest contributor to breaking the historical record of vaccine research and development.

With the continuous development of science, we have a deeper understanding of medical care. With the establishment and improvement of medical big data such as medical virus database and database, we have more references when facing viruses, and we can find the source of the virus in the first time, so as to carry out reasonable prevention and control and find a solution to the problem. Medical big data helps us solve problems quickly, which is the biggest contributor to our research and development of vaccines to break the historical record.

Second, the continuous progress of medical care has made our cognition and judgment more accurate, which is also the real reason for the shortening of vaccine research and development speed.

With the continuous progress of medical treatment, we have a deeper understanding of many viruses, medical workers' cognition has also been strengthened, the diagnosis of viruses has become more and more accurate, and the solutions have become more and more scientific. These are the reasons for the rapid development of vaccines.

3. What do you think of the record-breaking speed of vaccine research and development in COVID-19?

I think this is a good thing. It shows that the progress of medicine has indeed brought health and safety to everyone. This also shows the world's confidence in winning COVID-19. This is a very good thing, and it will really benefit everyone.
