Following the detection of the first domestic Omicron mutant strain in Tianjin on December 13, Guangzhou also detected a positive case of Omicron the next day

According to the World Health Organization, as of December 14th, 77 countries and regions around the world have reported Omicron mutant strains.

In order to avoid the possibility of a serious outbreak of the new crown epidemic in winter and spring, December 15, 2021, hosted by Yidao, Vaccine Esheng, and co-organized by Tencent Health, Zhihu, Vaccine Circle and other platforms, the 2021 world supported by CanSino Biotech Co.

Improving the immune barrier and improving vaccination strategies are imperative.

New coronavirus variants are emerging in endlessly.

Zhang Wenhong emphasized that the current overall global vaccine coverage rate is far from enough.

Precise prevention and control, no slack, sequential immunity against mutant strains, precise prevention and control, no slack, sequential immunity against mutant strains

"The adenovirus vector new crown vaccine has obtained very good scientific data in boosting vaccination and sequential immunization.

Real-world research: The sequential vaccination protection rate of the new crown vaccine can reach 95% Real-world research: The sequential vaccination protection rate of the new crown vaccine can reach 95%

At the meeting, Zhu Tao, Chief Scientific Officer of CanSino Bio, shared "The Value of Sequential Enhancement from a Vaccine R&D and Clinical Perspective".

Data shows that after 2 shots of inactivated vaccine, the third shot is boosted with adenovirus vector vaccine.

Inhaled new crown vaccine can provide multiple immune protection inhaled new crown vaccine can provide multiple immune protection

Recently, inhaled vaccines have attracted much attention because of their triple protection mechanism of humoral immunity, cellular immunity and mucosal immunity, and better antibody levels

According to the latest research, after inoculation with 2 doses of inactivated vaccines, one dose of adenovirus vector inhaled new crown vaccine is sequentially strengthened, and the titers of pseudovirus neutralizing antibodies against the Omicron mutant strain are only slightly lower than the prototype strain.
Compared with the three-shot inactivated vaccine, the neutralizing antibody titer is 10 times higher
.
This means that inhaled vaccines can still provide good protection against mutant strains
