On January 3, Beijing held a press conference on the prevention and control of the new crown pneumonia epidemic.
At the meeting, Wang Huaqing, chief expert of the China Center for Disease Control and Prevention's immunization program, said that the proliferation of the virus depends on living cells.
In the process of multiplication, the virus will mutate, and most of the mutations will rarely affect the pathogenicity of the virus, the sensitivity of the detection reagent and the effectiveness of the vaccine.
According to the latest information released by the World Health Organization, there is no evidence that virus mutations will affect the effectiveness of existing new coronavirus vaccines.
The World Health Organization is also continuing to pay attention to the mutation of the virus and assess its possible impact.
