On July 23, the State Council's joint prevention and control mechanism held a press conference. Feng Zijian, Executive Vice President and Secretary -General of the Chinese Prevention Medicine Association, said that the research and development of Ommaco mutations in Omi Coco is steadily advanced. It is required that the emergency use approval procedure can be started quickly to provide vaccination.

Feng Zijian pointed out that the State Council ’s joint defense and control mechanism science and technology group vaccine research and development special classes were listed on December 26, 2021, the WHO listed Omikon mutations as a major mutant plant, that is, organize expert research and judgment Essence At present, a number of technical routes have developed the development of unit prices and multi -price Omikon variants. The fast -moving unit price of Omikon variants has been approved by clinical trials and is conducting clinical trials in Zhejiang, Hunan, Hong Kong and other places. The rapid progress of tetramid restructuring protein vaccine has been approved by the Phase III clinical trial of the UAE, and related research has been launched.

Many other unit -prices, multi -price containing Omir Rongjuki, restructuring protein vaccine, adenovirus vector vaccine, and MRNA vaccine are also conducting pre -clinical research. Essence In addition, the special class also deployed the research on the new -spectrum vaccine, and the rapid progress of vaccine has been approved by clinical trials and launched related research.

The new coronal virus has been mutated. Is the existing vaccine valid for the Omikon variants? Feng Zijian said that the degree of mutation strains of Omikon has a large degree of mutation compared to various mutant strains before, and has a strong immune escape ability. It has a certain impact on the neutral and antibodies induced by the existing vaccines and previous infections. But immune protection not only depends on neutralized antibodies, but also related to cellular immunity and immune memory. The results of many studies show that existing vaccines at home and abroad have maintained high levels of severe illnesses and death effects. my country's vaccine has a good protection of the severe and death caused by the mutant strains of Omikon, and strengthening immunity can further reduce the risk of hospitalization, illness and death.

"Study on the prevention effect of domestic vaccine prevention in Hong Kong and the Mainland shows that the effect of vaccination with the protection of severe diseases and deaths is good. The study of the first University of Hong Kong shows that the elderly over 60 years of age complete two doses of domestic vaccines, which are for prevention and severe illnesses and severe illnesses and severe illnesses and severe illnesses and severe illnesses and severe illnesses and severe illnesses and severe illnesses and severe illnesses. The protection of death is 69.9%. After the third needle is strengthened, the effect of intensive and death can reach 97.9%. "Feng Zijian said.

冯子健指出，中疾中对3-6月内地发生的奥密克戎变异病毒感染病例的疫苗接种史分析显示，对完成全程接种和加强接种的18-59岁的感染者，由无症状感染、 The risk of light and ordinary development into severe illnesses decreases by 91%and 94%, respectively; those who are infected with a full vaccination and enhanced vaccination are reduced by 89 from ordinary and below. %And 95%.

Does the public need to vaccinate and inoculate the vaccine containing Omircong's mutation? Feng Zijian pointed out that this issue is not only in my country, but also internationally studying, mainly to study virus mutation and immune escape.
