First, the needs of economic development.
Not only is China constantly vaccinating COVID-19 vaccine, but other countries in the world are also rapidly vaccinating their nationals with COVID-19 vaccine, but China is obviously ahead of other countries in speed, because some countries have not even developed a relatively effective COVID-19 vaccine. However, once people in most countries in the world are vaccinated with COVID-19 vaccine, the world economy will once again circulate with each other, which is also in line with the needs of China's economic development.
Second, the normalization of COVID-19.
According to Professor Zhang Wenhong, COVID-19 will become a permanent virus in a period of time, and it will exist forever. Although the blocking probability of COVID-19 vaccine is above 90%, it is still not 100%. Therefore, people who have not been vaccinated with COVID-19 vaccine may still be infected with COVID-19 virus in the future. At that time, COVID-19 vaccine may not be free. Third, mask normalization.
For a long time in the future, our people may need to wear masks, because only when the vaccine protection rate reaches more than 70% can an effective immune barrier be formed. So if you don't get vaccinated at this time, you will still need to wear a mask for a long time to come, and you will still be in a state of psychological panic, because at that time, you can't tell whether others have written about COVID-19. What do you think this time? Welcome to comment.
