COVID-19 vaccine only needs 1 needle to start vaccination in Shanghai. Is it different from the previous vaccine?

According to relevant personnel, COVID-19 vaccine, which only needs one shot, began to be inoculated in Shanghai. So what's the difference between this vaccine and the previous vaccine? There must be a difference. His main difference lies in the different working principles of vaccines and different inoculation methods. This one only needs one shot, and the others need two shots, but the effect can be basically the same. And the purpose is the same, is to produce antibodies in the body, and to prevent infection with COVID-19. Yes, after more than a year of contact. We are very familiar with COVID-19. In order to defeat COVID-19, we have made a lot of efforts and achieved a lot of good results. Only true universal vaccination can achieve universal immunization, which makes our influence on COVID-19 really strange. But in real life, this is often different from what we think. Many citizens don't cooperate with vaccination. Why did this happen? Let's take a brief look together.

The first is a big reaction. According to relevant personnel, people who have been vaccinated have a bad reaction. Therefore, everyone has scruples about vaccination, and it is very wrong to be afraid of other injuries. After all, it can be promoted and natural safety is guaranteed. You don't have to worry, don't worry, just get vaccinated.

Secondly, vaccination is very troublesome. Although the process of vaccination is simple, it is very troublesome, because everyone concentrates on vaccination and often needs to queue for a long time. Many people, because of trouble, don't want to wait, so everyone simply doesn't get vaccinated.

Of course, there are many other reasons besides this one. Everyone has a different idea anyway. However, no matter what you think, you can't change this result. It is only a matter of time before vaccination is fully covered. I hope everyone will actively cooperate and advance this date.
