On the evening of May 4, Academician Zhong Nanshan connected with overseas students to answer questions for international students against international epidemics. On the line, Zhong Nanshan expressed his disapproval of "group immunization", saying that it would be possible to achieve "group immunization" at the expense of many talents.
Zhong Nanshan, academician of the Chinese Academy of Engineering: In Europe, 20% of people have antibodies, and the highest reported is 25%. This number is far from the so-called group immunity. This disease (New Coronary Pneumonia) is generally immunized. It usually takes 6 to 70% of people to become infected. This is now possible, but now more than 20% is far from being reached. I don't quite agree with this approach. Many people have to be sacrificed. Even 1% is more than ten to twenty times higher than the flu, and even one hundred times. If you are 2%, 3%, that is even more terrible, because you have to sacrifice a lot of people to get group immunity. I don't think that this method is feasible. We have many ways. We can prevent it, we can protect it, we will fight for time and make vaccines.
