reporter learned today from Kexing holding Biotechnology Co., Ltd., in September 5th, the China Academy of Sciences researcher Wang Xiangxi worked with Peking University and Kexing holdings to publish the paper on the international research platform medRxiv. Inoculation of third inactivated vaccine can enhance the effectiveness, broad-spectrum and sustainability of COVID-19's recall response. Through serological analysis of Xinguan early rehabilitation patients and volunteers inoculated with 2 and 3 doses of inactivated vaccine, it was found that the serum samples inoculated with 3 doses of inactivated vaccine showed more rapid immune response, more lasting humoral immune response, and more broad-spectrum neutralization ability to many mutant strains, including delta strain. This provides a theoretical basis for the vaccination of the third dose of inactivated vaccine P>
novel coronavirus pneumonia volunteers were recruited, 6 healthy volunteers and 38 volunteers who received 2 or 3 doses of Corning new crown vaccine, Kerr rifle, in the study. 22 volunteers were recruited. The ages of all volunteers ranged from 16 to 69, with a median of 33. None of the volunteers who had been vaccinated by Kerr had infected COVID-19 before participating in the study. In the p>
study, the blood samples collected from the rehabilitative volunteers 1.3 months after the infection and at a specific time point after Kerr's rifle vaccination were compared. p> < p > the results showed that the neutralization titers of blood samples from patients inoculated with 3 doses of kelefu to several variant strains such as beta and delta decreased little compared with those of convalescent patients and those inoculated with 2 doses of new crown vaccine kelefu. Thus, the third dose vaccine can enhance the neutralization breadth of the new crown virus and increase the potential to effectively resist the mutant strain. The study also found that the antibody binding activity to the mutant strain caused by 3 doses of Kelaifu was wider than that of 2 doses of Kelaifu vaccinated and rehabilitated. The third dose of enhancer could cause a rapid, powerful and lasting immune recall response p> < p > the above information shows that after 6 months of inoculation with two doses of kelefu, the third dose can quickly induce more comprehensive antibody types, and also show good cross neutralization effect on variant strains such as alpha, beta, gamma and delta p> < p > by the end of August 2021, Kexing had supplied more than 1.8 billion doses of new crown vaccine to nearly 50 countries around the world, including China, with a cumulative vaccination volume of 1.4 billion doses. The company's Kelaifu vaccine is the new crown vaccine with the largest domestic supply and use, and China's new crown vaccine with the largest export p>
