New research, in which scientists from Queen Mary University of London participated, found evidence of protective immunity in people after mild or no symptoms formed after 4 months, and analyzed the study, which was published in the journal Science Immunology Antibody and T-cell responses in 136 London healthcare workers who had mild or asymptomatic infection with Corona dating back to March 2020.
The team, which includes researchers from Queen Mary, Imperial College London and University College London, found that 89% of health care workers who were screened carried equivalent antibodies 16-18 weeks after infection.
And the researchers found that most of them also contained cells T Able to recognize multiple different parts of the virus, but the two responses did not always go hand in hand, as some individuals showed T-cell immunity, but there is no evidence of antibodies, and vice versa.
According to the researchers, this is good news, and it means that if you have been infected, there is a good chance that you have developed antibodies and T cells, which may provide protection if you encounter the virus again.
Joseph Gibbons, Postdoctoral Research Assistant at Queen Mary, said: “Our study of Corona infection in healthcare workers in London hospitals reveals that 4 months after infection, about 90% of individuals have antibodies that prevent the virus.”
The most encouraging thing is that 66% of health care workers see that their levels of these protective antibodies are high, and that this strong response to antibodies is supplemented by the T cells that we see interacting with different parts of the virus.
