In view of the current COVID-19, Zhong Nanshan, Wu Zunyou, Zhang Wenhong and other experts suggest that the vaccine can fight as soon as possible.

At present, more than 110 million doses of new crown vaccine have been inoculated in China. However, due to the large population base in China, there is still considerable space to form an immune barrier.

So why should we get vaccinated as soon as possible? Experts pointed out that everyone is susceptible to the new coronavirus, and everyone needs to be vaccinated with the new coronavirus vaccine. The new coronavirus vaccine is effective, and the final victory of mankind over the new coronavirus depends on the vaccine.

Experts said that in general, the stronger the infectious power of infectious diseases, the higher the population immunity is needed. The population immunity is directly proportional to the protective effect of the vaccine and the vaccination rate.

Therefore, in order to achieve adequate population immunity, we need to have a high enough vaccination rate, that is, the vast majority of people are vaccinated. On the contrary, if more people are not vaccinated or most people do not want to vaccinate, it will not form a solid immune barrier. When there are infectious sources, it is easy to spread the disease.

It should also be noted that at present, why do young people get vaccinated first and then old people get vaccinated,In this regard, Dr. Zhang Wenhong introduced: ① the elderly go out less, it may not be easy to be infected; ② the main task of epidemic prevention and control in China is external prevention, import and internal anti rebound, and doctors and other people who are easy to contact with the virus are mostly young people; ③ the incidence of other diseases in the elderly group is high, which needs more clinical research data support.

Experts stressed that it is generally believed that only when the vaccination rate reaches 60% or even 70% can the vaccine establish protection for the whole people. In view of the good safety and effectiveness of the vaccines that have been approved in China, it is advocated that the people should actively participate in vaccination on the premise of informed consent and exclusion of contraindications. This is not only to protect themselves, their families and others, but also to contribute to the global epidemic prevention and control.
