Scientists have resettled with British medical professionals in contact with “Covered” patients, special immunity to coronavirus, which cannot be determined through antibodies. This is stated in the study published in the scientific journal Nature.
They conducted a study of immunity about 60 employees of one of the clinics in the UK on the level of antibodies and hidden infections. According to the results of the anlizes, it turned out that in four months their PCR tests were always negative, but there was no antitheos to coronaviru in their blood, even if their colleagues in the clinic were infected with COVID-19.
After having studied the blood of the subjects, scientists were determined in 20 of them an increased concentration of T cells, and in 19 people discovered an additional immune protein called IFI27. Theoretically, he may indicate that their organism has already in contact with COVID-19.
Scientists assume that immunity of such people responds so quickly to Coronavirus, that he cannot even leave the antibodies. At the same time, such powerful protection could well develop after contacting the health workers and with other previously known human coronaviruses, which cause colds.
Previously, Academician of the Russian Academy of Sciences Vadim Pokrovsky stated that the security from COVID-19 does not depend on the number of antibodies in the body. “In fact, there is no direct connection between the number of antibodies and protection against coronavirus. Here more complex cellular immunity is connected. But they chose such averaged indicator, which takes the basis of the provision of codes,” he said.
