According to the wisdom of Changsha news, the Hunan Center for Disease Control and Prevention conducted the whole genome sequencing and sequence analysis of the new coronavirus on december 16 on the respiratory specimens of the new coronavirus infected people imported from outside our city, and after review by the Chinese Center for Disease Control and Prevention, it was confirmed that the New Coronavirus Omiljung variant (B.1.1.529 evolutionary branch) was detected.
The two cases of the new coronavirus Omiljung variant are infected by the entry closed-loop control personnel, and are currently isolated and treated in designated hospitals.
In the early morning of December 17, Dr. Zhang Wenhong spoke out through his Weibo, and the international Omilon epidemic was confusing and China responded in an orderly manner. Dr. Zhang Wenhong posted on Weibo that it is only time to beat the virus, and there is no need to panic. China's third dose of vaccination can still retain the neutralizing effect on Olmiqueron and Delta, with the potential to reduce the incidence of severe cases. China's follow-up third dose of vaccine optimization strategy is expected to be fully completed in 2021.
In addition, Zhang Wenhong also said that the current is the most difficult time in the world, and it is the most difficult time for human beings to fight against the virus. China's dynamic zeroing strategy, known as PHSM (Public Health and Social Measures), has been widely adopted internationally for the current Opmi-Krong response. China's follow-up third dose of optimized vaccination strategy is expected to be fully completed in 2021, and it will enter 2022 together with the international community. In what WHO calls the total control of COVID-19, people around the world will embrace ordinary and stable lives.
According to Zhang Wenhong, the Hong Kong team's research on Omiljung is about to complete the international peer review, and the study makes an important judgment: the virus has significantly evaded 2 doses of vaccination and can no longer block the spread of the virus. The level of intrabronchial replication of the new virus is significantly higher than that of Delta, and the rate of transmission is significantly increased on the basis of Delta. At present, without further tightening public health and social measures (PHSM) such as school closures, it will be difficult to stop the rapid spread of Aumicron and defeat Delta.
According to the previous news of @First Financial Daily, it was learned from Sinovac that Kexing has obtained two strains of Omicron virus from Hong Kong, that is, neutralization tests have been carried out.
The latest laboratory findings show that the immune serum of 20 doses of CoronaVac and 48 doses of CoronaVac was tested for neutralizing antibodies using one of the strains of Omicron, with a positive rate of 35% (7/20) of serum neutralizing antibodies after 20 doses of two doses of vaccine and a positive rate of serum neutralizing antibodies after 48 doses of three doses of vaccine (45/48).
The above results show that the vaccination of the third dose of vaccine can effectively improve the ability of serum to neutralize the Omicron virus strain. Comparative testing with another strain of Omicron virus is underway; companies are conducting further studies of serum at more post-immunity time points and at different antibody levels to obtain a comprehensive evaluation of the effects of the Omicron strain on the vaccine.
