Researchers in the UK said that they have observed a “substantial” drop in the proportion of people with antibodies to the new coronavirus, which may mean that “immunity is fading.” Scientists at Imperial College London University found in this study that the coverage of virus antibodies is declining. According to Reuters , the proportion of the UK population with antibodies dropped from 6% in June to 4.4% in September . According to CNN, researchers randomly selected more than 365,000 people in the UK and distributed finger blood test kits. After testing, they concluded that “the proportion of the population with detectable antibodies has dropped significantly.”
According to Reuters, Wendy Barclay, director of the Infectious Diseases Center at Imperial College London, said: “According to our understanding of other viruses, the comparison of evidence shows that immunity and antibody levels will decrease simultaneously, which indicates that the British population is immune to the new crown. The force is fading.” The specific antibody the researchers looked for in this study was immunoglobulin G. CNN pointed out that other studies have shown that “other types of antibodies may last longer than immunoglobulin G. ” .
But Helen Ward of Imperial College London, told the BBC News Channel that research shows that “immunity fades quite quickly.” Ward also said in a statement: “We don’t yet know whether this will put people at risk of being re-infected with the new coronavirus , but it’s important that everyone continues to follow the guidance on epidemic prevention and control to reduce their own and The risk of infection for others.”
