For the formation of herd immunity, a number of factors must be observed. This statement was made by the academician of the Chinese Academy of Engineering Sciences, leading specialist in respiratory diseases Zhong Nanshan.
Achieving natural immunity from COVID-19 is unrealistic, anti-scientific and inhuman, he said. First of all, mass vaccination is needed for its formation, writes RIA Novosti. In addition, countries should cooperate among themselves on this issue.
If these conditions are met, Zhong Nanshan believes, herd immunity can develop in one to two years. It is too early to talk about the imminent formation of collective immunity to coronavirus.
Earlier, the infectious disease doctor named the regions of Russia where the highest level of collective immunity to COVID-19 is observed, and also listed the factors that can contribute to its formation. According to him, the Russian winter is extremely favorable for the spread of this kind of virus. However, if mass vaccination soon begins in the country, the Russians will “calmly meet the spring period,” avoiding the third wave of coronavirus.
