Coronavirus: Infected people are immune for only a short time


A study from Britain raises doubts about possible lifelong immunity after a Covid-19 infection. Antibodies to the novel coronavirus fell rapidly in the British population in the summer, according to a study by Imperial College London released on Tuesday. This suggests that protection after infection may not last long.

Scientists looked at the level of antibodies in the UK population after the first wave of infections in the spring. As a result, the spread of antibodies dropped in 6% of the population at the end of June, reaching only 4.4% in September. There have been fewer changes in antibody levels among healthcare workers, possibly due to their repeated exposure to the virus.
