British people’s antibody levels to the new coronavirus dropped rapidly in the summer, a British study found on Tuesday. This suggests that even if infected with the new coronavirus, the immune protection provided may not last for a long time, which increases the possibility of community immunity decline. The study found that the antibody retention rate decreased from 6% at the end of June to 4.4% in September. This increases the possibility of a decline in the immune capacity of the population before the second wave, which in recent weeks has forced local governments to take restrictive measures. According to the report, < / P > < p > scientists’ understanding of the immune problem of NCV is still complex and vague. Human immunity may be assisted by T cells and B cells. After the human body contacts the virus again, the cells are stimulated to produce antibodies rapidly. Experience with other coronaviruses suggests that immunity may not last, the researchers said. Wendy Barkley, director of infectious diseases at Imperial College London, told reporters: “we can see that antibody levels are falling and we know that antibodies themselves have a strong protective effect.” < / P > < p > “based on what we know about other coronaviruses, it seems that the rate of decline in immunity is the same as that of antibodies, which is a sign of decreased immunity in the population.” She said. Barkley said that although the antibodies produced by the infection will decrease rapidly, it does not necessarily affect the effectiveness of the vaccine candidates currently in clinical trials. gather and watch!
