A detailed comparison of COVID-19 cases has finally shed light on why some people escape infection. It turns out that a team of scientists has identified previously unknown immune responses, paving the way for new treatments.
Since the appearance of the COVID-19 pandemic, many patients have suffered from a particularly severe form of the infection due in particular to a panic in the immune response, this reaction which is responsible for fighting infections. . Still others have reported persistence of symptoms beyond the usual Covid-19 recovery period. Conversely, some people escape contamination even though they are exposed to the SARS-CoV-2 virus like the rest of the population. These specific cases are of great interest to the scientific community because apart from scrupulously respecting barrier gestures, the explanation could lie in immunological and genetic factors. However, many elements still remain to be discovered on this subject. But according to researchers from the Wellcome Sanger Institute, University College London (UCL), Imperial College London and the Dutch Cancer Institute, people capable of repelling SARS-CoV-2 may indeed have unique immune responses. which help them avoid prolonged infection.

Their study published in the journal Nature indeed reveals that differences in immune response could explain why some people seem to reliably escape infection. His…
