China Southern Finance and Economics, December 4th. At the Second Greater Bay Area (Shenzhen) Vaccine Summit, Zhong Nanshan, an academician of the Chinese Academy of Engineering, pointed out in his speech about the intensified injection after the entire course of vaccination. , The third dose of vaccination is effective and proved to have enhanced clinical protection in the real world. In addition, after two doses of inactivated virus vaccine, the mRNA vaccine is effective, after two doses of inactivated virus vaccine, the subunit protein vaccine is effective, and after two doses of inactivated virus vaccine, the adenovirus vector vaccine is effective. .

Zhong Nanshan clearly pointed out that the effect of vaccination with different types of vaccines may be better, but the protection rate needs to be further observed in the real world to confirm.

Regarding the existence of the mutant strain of the new crown virus that South Africa has previously announced, whether it is necessary to replace the strain for the development and inoculation of related vaccines, Zhong Nanshan said that it is not difficult to replace the vaccine strain, but the cost is very high. Need to observe the infectivity and pathogenicity of the variant virus. Some information from South Africa currently shows that the current pathogenicity seems to be not very strong. If the pathogenicity is not significant, there is no need to adjust the strain and re-developing a vaccine for the time being. But still need to continue to observe the situation after two or three weeks. (21st Century Business Herald)
