China Prevention Medicine Society: Whether you need to vaccinate and when to vaccinate the Vaccine containing Omir Rongjon variants, still study

On July 23, the State Council's joint prevention and control mechanism held a press conference to introduce the relevant situation of the safety effectiveness of the vaccine of the new coronary virus. At the meeting, a reporter asked that since the epidemic occurred, the new coronary virus has been mutated. Is the existing vaccine still valid for Omikon's mutant strains? What is the progress of my country's research and development of Omikon's mutation vaccine? In this regard, Feng Zijian, Executive Vice President and Secretary -General of the Chinese Association of Prevention Medicine, said that my country's vaccine still has a good protective effect on the severe illness and death caused by the mutant strains of Omikon.

Feng Zijian said that compared with the previous mutant strains, Omikon's mutant strains are indeed relatively large, and the immune escape ability is relatively strong. It must have an impact. But immune protection not only depends on neutralized antibodies, but also related to cellular immunity and immune memory. Therefore, the results of many studies show that the effects of existing vaccines at home and abroad still maintain a high level. my country's vaccine still has a good protective effect on the severe disease and death caused by the mutant strains of Omikon, and strengthening immunity can further reduce the risk of hospitalization, severe and death.

Feng Zijian pointed out that the real world research on the prevention effect of domestic vaccines in Hong Kong and the Mainland showed that the effect of vaccination with the protection of severe and death is still good. A study by the University of Hong Kong shows that the elderly over 60 years of age to complete the two doses of domestic excessive vaccines are 69.9%of the protection of severe illnesses and deaths. After completing the third pins, 97.9%.

According to reports, the China Center for Disease Control and Prevention is mainly the analysis of the history of vaccination history of Omikon mutant infection in the Mainland in March to June this year. The risk of developing from asymptomatic infections, minor, and general types to severe illnesses decreases by 91%and 94%respectively; those who have infected and enhance inoculation of the whole process of inoculation and inoculation are completed from ordinary and below to infection. Those who reduce 89%and 95%respectively.

Regarding the vaccine research and development of the mutant strains, Feng Zijian introduced that from December 26, 2021, the State Council ’s joint defense and control mechanism science and technology group vaccine group listed Omikon mutant strains as a mutant strain. That is, organize experts to study and judge and work to deploy R & D work. 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 the tetraonal 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 Omiro Rong mutant live vaccines, reorganized protein vaccines, adenovirus vector vaccines, and MRNA vaccines 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.

Feng Zijian said that the research and development of Omikon's Vaccination of Omikon's mutation is steadily promoted. As long as there is a need, in accordance with relevant regulations, it can quickly start emergency use approval procedures and provide vaccination. As for whether it is necessary to vaccinate and when to vaccinate the Vaccine containing Omircor's mutant strains, this problem is not only in my country, but also internationally study. It is mainly to study the situation of virus mutations and immune escape.
