A study conducted by Imperial College in London warned that people are not immune to the Corona virus just because they have proven the presence of antibodies in their bodies.
The study published in the Mirror newspaper estimated that only 4.4 percent of adults had some form of immunity against Corona last September when the cases began to worsen again.
The number of people with antibodies decreased by 26.5 percent over three months, indicating a decrease in antibodies in the weeks or months after the person was infected.
And between June 20 and September 28, the percentage of people carrying antibodies decreased from 6 percent to 4.4 percent.
The study pointed out that people who did not show symptoms of Corona are likely to lose the antibodies that can be detected sooner than those who showed signs of the disease.
Professor Paul Elliott, director of the React program and one of the study’s supervisors, said: “Our study shows that over time there is a decrease in the percentage of people who have been shown to carry antibodies to the virus that causes Covid 19,” while Helen Ward, one of the main authors of the antibody report, said: “This study showed that The percentage of people who have antibodies can decrease over time ... We do not yet know whether this will leave these people at risk of reinfection with the virus, but it is imperative that everyone continues to follow the instructions to reduce the risks to themselves and others.
