Beijing News Shell Financial News (reporter Song Meilu) On the morning of September 25, the plenary meeting of the 2021 Zhongguancun Forum was held at the Exhibition Center of the Zhongguancun National Independent Innovation Demonstration Zone in Beijing, and Xie Xiaoliang, a lecturer at Peking University Li Shaoji, delivered a speech on the theme of health and epidemic prevention at the meeting, he said that the emergence of mutant strains has made most of the vaccine neutralizing antibodies ineffective, but this does not mean that the vaccine is completely invalid, the other half is still effective, but the efficacy has been reduced. At present, an effective measure to avoid a virus breakthrough infection is to strengthen the third dose of vaccine.
Xie Xiaoliang said that even if the third booster injection is given 12 months after the second dose of inactivated vaccine, it can still awaken immune memory within 7 days and can effectively resist the delta variant strain. At the same time, he also stressed that the best time to receive the third injection is 6 months after the second injection, and the potency can last for at least 9 months.
He said that for the mutant strain, a full-spectrum antibody drug that is sufficient to resist all existing major variant strains has been developed to be a single (rather than paired) antibody drug, and can also effectively deal with new variants that may appear in the future.
