Zhong Nanshan said that China can establish effective group immunity. How many people need to be vaccinated to establish group immunity?

The COVID-19 epidemic has changed our lives, and it seems that we can never go back to the time when we used to go abroad by plane. However, although the COVID-19 epidemic can't die out, we also have a solution, that is, universal immunization. We can open the door and the world can recover from the past. Now it is obviously not the time to open the country, because our group immune barrier has not been built yet. Even a few cases of foreign imports can lead to the local rebound of the epidemic situation in China, which is enough to show that the vaccination rate in China has not yet reached the level of building an immune barrier.

How many vaccines do we need to vaccinate to establish group immunity? Academician Zhong Nanshan said that taking the population of 654.38+400 million in China as an example, as long as the vaccination rate of the second dose reaches 80%, then we can establish an immune barrier. Many people think that COVID-19 is constantly changing, so vaccination is useless. This idea is very foolish, and it has been proved that COVID-19 vaccine has the same protection rate against the mutated virus. Academician Zhong Nanshan took the Guangzhou epidemic as an example, that is, the inactivated vaccine is still effective against Delta virus, with a protection rate as high as 60% and a protection rate of 100% for severe cases. In a more popular way, even if you are infected with COVID-19 vaccine, it is a mild disease, not a serious one.

Vaccination Vaccination can not only protect yourself, but also protect others. Vaccination is a responsible attitude towards people. There are still many people who are holding a wait-and-see attitude towards COVID-19 vaccine, and the delay in vaccination with COVID-19 vaccine is a huge obstacle for us to establish an immune barrier. Therefore, we call on everyone to vaccinate in time and build an immune barrier as soon as possible.

Netizens talked about COVID-19 vaccine, and they expressed their gratitude that it was born in China. Fortunately, they are from China and can receive free vaccination and treatment. How lucky they are!
