The client of Chinanews.com, April 10 (Song Yusheng) On the 10th, a member of the high-level expert group of the National Health and Health Commission Zeng Guang made a video interview with Chinanews.com. Speaking of the "group immunization" proposed by relevant countries, Zeng Guang said that it is "book business spirit" to propose "group immunization". It is a theory, and when this theory is turned into practice is very scary. "No country is currently implementing 'group immunization', and they are adjusting to the direction of strict prevention and control. They have also closed the city, banned their feet, and even proposed that there should be no more than two people gathering, which is stricter than China." He said, "Group "Immunity" is a theory that does not work in practice.
