A UK study nurtures Doubts about possible permanent immunity after a Covid-19 infection. Antibodies to the new coronavirus have declined rapidly in the British population over the summer, according to a study published by Imperial College London on Tuesday. This suggests that protection after an infection may not last long.
The scientists examined the level of antibodies in the UK population after the first wave of infections in the spring. Consequently, the spread of antibodies dropped in six percent of the population in late June to just 4.4 percent in September. Healthcare workers have had fewer changes in antibody levels, which may have been theirs. repeated exposure to the virus must be.
In the professional world, rare cases of a second corona infection have already raised questions about immunity to the virus.. A study by the Chinese University of Chongqing had already shown that the The amount of antibodies in the blood of recovered Covid-19 patients decreases significantly within two to three months. can.
Experience with other coronaviruses suggested that immunity may not last long, scientists at Imperial College said. The scientists emphasized that the rapid decline in antibodies does not necessarily impact the effectiveness of corona vaccine candidates currently in clinical trials. “A good vaccine could be better than natural immunity.”
