Regarding the vaccine booster, experts have the latest research and judgment!

　　As the "delta" variant strain spreads globally, the public is also concerned about whether people who have completed the vaccination still need to be vaccinated with booster shots?

　　Recently, Zhong Nanshan, an academician of the Chinese Academy of Engineering, made the latest research and judgments on topics such as the effectiveness of Chinese vaccines, enhanced needles, and delta strains when attending a health industry forum.

　　"Inactivated vaccines or mRNA vaccines, half a year after vaccination, the immune function has been significantly reduced. Various countries are discussing how to strengthen the immune effect of vaccines. Countries that vaccinated inactivated vaccines and mRNA vaccines have tested 6 after two doses. One more dose every month will have the effect." Zhong Nanshan said.

　　According to the latest domestic research data, if another dose is given 6 months after the second dose of vaccine, the antibody level has increased significantly by more than 10 times, and it will remain at a relatively high level 6 months after vaccination.

　　"It looks like this is a very promising method of boosting immunity." Zhong Nanshan said that at present, the data on the level of boosted immunity after the mRNA vaccination abroad has not yet been counted, and the protective effect of domestic booster vaccination in the real world has yet to be further proved.

　　Regarding the issue of enhanced acupuncture, Zhang Yuntao, chief scientist of Sinopharm China Biotechnology, said in an interview with the media recently that when Sinopharm conducted phase I and II clinical studies last year, it had designed an enhanced acupuncture trial, and related data had been announced recently.

In the three age groups of 18 to 59 years old, over 60 years old, and 3 to 17 years old, the designed vaccination program is that the interval between the third and second injections is 56 days.

　　"The overall safety data is still very good. Whether it is a local reaction or a systemic reaction, it is in line with expectations, and it is no different from the two injections." Zhang Yuntao said that in terms of immunogenicity, after the third injection, the antibody The growth rate is around 30%.

　　Regarding which groups of people should be given priority to vaccinate the booster shot, Zhang Yuntao said that the relevant vaccination plan has been discussed, and it should be some special groups, such as the elderly over 60 years old, and the people who are most closely in contact with social and economic activities, including aviation industry personnel and express delivery personnel.
