COVID: who has had it is IMMUNE for the rest of LIFE. The Discovery in the BONE MARROW

Who has had it is IMMUNE for the rest of LIFEThose who have contracted COVID-19 are immune thanks to a type of cell detected in the bone marrow capable of persisting healing beyond 11 months. This is the sensational discovery that could revolutionize the history of Sars-CoV-2.

The study, as reported by Il Messaggero, comes from Washington University di St. Louis, United States, and provides evidence that the immunity triggered by Sars-CoV-2 infection could be extraordinarily long-lasting. Published in the prestigious international magazine Nature come on PubMed, the paper opens a window to the possibility of getting out of the pandemic faster than we thought. We knew that antibodies against Sars-CoV-2 they tend to decrease over time after recovery but in the study the US researchers explain that they have traced cells, in the body of sick patients, that they survive for a long time (it is not yet known how much but for a long time) and certainly more than the time since the pandemic was declared worldwide. Their peculiarity is that they make the antibodies survive in the case of the presence of viruses in general.

In the study the Missouri scientists subjected to analysis of 77 patients who had developed a moderate form of Covid, trying to analyze how the antibody levels evolved, the so-called IGGs. Among the volunteers in 18 they also provided a own bone marrow sample to identify these so-called long-surviving plasma cells. In the case of the people analyzed, the Iggs were present even after 11 months compared to a decrease in the value of traditional antibodies over time. The study was led by B cell immunologist Ali Ellebedy, who spoke to the British magazine: “A plasma cell is our life story, in terms of the pathogens we have been exposed to. “

The Ellebedy team from Washington University in St. Louis, Missouri also observed that the same cells are also activated at Pfizer’s mRNA vaccination. But the persistence of antibody production general, caused by vaccination or infection, does not guarantee lasting immunity to Covid.
