(Fighting against New Coronary Pneumonia) Zhong Nanshan: China should adhere to the "dynamic clearing" strategy without fear of Omi Keron strain

  China News Service, Shenzhen, December 4 (Reporter Tang Guijiang and He Junjie) The 2021 Greater Bay Area Vaccine Summit was held on the 4th in Pingshan, Shenzhen.

Zhong Nanshan, an academician of the Chinese Academy of Engineering, said in an online meeting that China should adhere to the "dynamic zeroing" epidemic prevention strategy and more precise prevention and control, and there is no need to be afraid of the Omi Keron strain.

  On the same day, about 1,000 representatives from the disease control department, the Greater Bay Area, international organizations, industry enterprises, academia, and the media participated through a combination of online and offline methods to discuss how to be global in the first year of the "14th Five-Year Plan". Strengthen cooperation at the level to further improve the level of disease prevention and control; Zhong Nanshan participated in the discussion via video that day.

  Zhong Nanshan said that the Omi Keron variant spreads faster and is more contagious, but how harmful it is depends on the situation. Current data show that it seems that most patients have mild symptoms.

Compared with this mutant strain, what is the protection rate of the existing vaccine?

Zhong Nanshan responded that China is intensively conducting research.

  Regarding the "immune escape" that the Omi Keron mutant may bring, Zhong Nanshan believes that the current inactivated virus vaccine has the widest coverage of antigens. "I don't think the vaccine's protection against the Omi Keron mutant will be completely ineffective. Isn't it? Now that the vaccine virus strain is replaced immediately, I think it is necessary to observe the spread of Omi Keron and whether the pathogenicity is so terrible."

  Zhong Nanshan said that according to the feedback from South African doctors, the symptoms of Omi Keron infection are relatively mild, so there is no need to adjust the virus strain urgently. It will take about two or three weeks to see the development trend of Omi Keron virus.

  Zhong Nanshan introduced that according to overseas media reports, compared with the tens of thousands or hundreds of thousands of previously reported cases of the new crown, the current number of reported cases of Ome Keron is not too high, but most countries still attach great importance to it. It even implemented measures to "close the country".

Zhong Nanshan said that China should still treat this new variant objectively, adhere to the "dynamic clearing" epidemic prevention measures, and take further precise prevention and control, and there is no need to be afraid of the Omi Keron strain.
