<h1 toutiao-origin="h1" > Zhong Nanshan: Effective, very safe</h1>
Is the domestic vaccine useful for the Delta strain? "Effective, very safe." Zhong Nanshan said firmly that he used a set of verified scientific data to illustrate.
Judging from the clinical immunization results, in response to the new coronavirus variant strain, the positive transpositivity rate of the immune serum vaccinated with the Kexing new crown inactivated vaccine on the Delta variant decreased slightly, reaching 87.5%; while the Sinopharm vaccine had the protective ability of the alpha strain, beta strain and delta strain, and the neutralization ability of the alpha strain decreased by 6.7%, and the protective ability remained basically unchanged; the neutralization capacity of the beta strain and the Delta strain decreased by 47% and 32% respectively. "The laboratory examination of these Chinese vaccines found that their overall killing power against the virus has decreased, but it still has a protective effect." Zhong Nanshan said.
According to him, based on the study of the outbreak of the new coronavirus Delta variant in Guangzhou in May this year, the results proved that the domestic vaccine has a protective effect. Preliminary statistics show that the protective effect of vaccines on severe diseases is 100%, and the protective effect on moderate, mild and asymptomatic is 76.9%, 67.2% and 63.2%, respectively. The relevant research results will be published in the future.
In Zhong Nanshan's view, natural immunity is unrealistic, unscientific, and inhumane. "Mass vaccination to achieve herd immunity requires a global collaboration of 2 to 3 years. At present, the number of vaccines in China is the largest, but due to the large population base, the proportion of vaccines per 100 people in China is not high. In China, 83.3% vaccination rates are needed to reach herd immunity. Zhong Nanshan believes that the next step should be to accelerate vaccination and accelerate the development of a vaccine that is more effective for the infection of the Delta variant.
