Zhong Nanshan: Omicron is not so terrible. The key is to do a good job in prevention and control

With the rapid spread of the mutant COVID-19, the multinational emergency escalation and prevention measures. Is Omicron really that terrible? Is the current vaccine still useful? Need to replace vaccine targets? The second Dawan district (Shenzhen) vaccine summit opened in Shenzhen today (4th). At the forum held this afternoon, academician Zhong Nanshan said that Omicron is not so terrible. The current vaccine still has protective effect. It has to be observed for two or three weeks whether the target of the vaccine needs to be replaced. At present, the key is to do a good job in prevention and control.

Academician Zhong Nanshan said that the infection of Omicron strain must be stronger, but its pathogenicity is not so strong. From the feedback from South Africa, most patients have relatively mild symptoms. Will the protection of the current vaccine be reduced? This is under intensive research.

But in general, academician Zhong Nanshan said, I think China's dynamic zeroing method is very effective. We don't need to be afraid of this Omicron. According to reports from many countries, the number of cases is more than a dozen or dozens, while tens of thousands of cases can appear in the past day, Novel coronavirus pneumonia is a novel coronavirus pneumonia. "Our country adopts an objective and dynamic zero clearing method. So my view is that prevention of new crown pneumonia is the main prevention and control measure and the key to controlling the new crown pneumonia epidemic."

As for whether the protective efficacy of the vaccine will be reduced and whether it is necessary to urgently replace the strain target of the vaccine, academician Zhong Nanshan said that it is not necessary to replace the strain immediately. First of all, our virus inactivated vaccine is relatively reliable. It covers a wide range of antigens and will not be completely ineffective for Omicron. "I know that several large vaccine companies have begun to prepare to develop new vaccines. It should not be difficult to change this, but it is not necessary to change it quickly. I think we should observe it." Academician Zhong Nanshan said that the first thing is to look at the spread of Omicron and the pathogenicity of Omicron. If he is not so terrible, there is no need to change it immediately, and we will treat it slowly like influenza. "So I don't think it's a time for urgent adjustment. It's about to look at its development trend in two or three weeks."
