This is how scientists explain these cases.

This is one of the events that is challenging people because they are failing to find an answer, but science has an answer.

Researchers from around the world, led by the University “Rockfeller” in New York, have found that a percentage of the infected cannot produce the responsible molecule protecting them from the viruses that attack the body.

 We focused on seriously ill persons and found that there are 10 to 12 percent of cases that have a particular genetic characteristic, which makes their body unable to produce interferone, the first protective molecule”- says Giuseppe NOvelli, a doctor at a polylinkic in Rome and the president of the phons “Giwanni Lorzini” in Milan.

Additionally, the study speaks of other genetic changes that bring resistance to the virus to a handful of people who are supposed to have natural immunity to David-19.

“munity is not created only by antibodies. There is also so-called cell immunity. In this case it is essential to study lymphocytes. We have what we call natural immunity, mediated by cells, in which the cell immune system, can protect you many times longer than antibodies that can disappear”Says Roberto Luzat, professor of infectious diseases at the University of Trieste.
