Scientists of the Royal College of London found out that people with a high level of T-cells from the usual cold are less susceptible to coronavirus infection. The results of the study are published in the scientific journal Nature Communications.
The study began in September 2020, when most of the residents of Great Britain have not yet become coronavirus and were not vaccinated from COVID-19. Scientists investigated 52 volunteers who lived together with an infected person. Participants handed over PCR tests on the fourth and seventh day after contact.
Blood tests were taken within six days after they came to contact with patients. This made it possible to analysts to analyze the levels of the t-cells that were developed by other ordinary coronaviruses causing colds.
It turned out that 26 volunteers who have not become infected, the level of these T cells was significantly higher than the remaining participants in the study that were infected. “To protect against the virus, these T cells attack proteins inside the COVID-19 virus, and not a spike protein on the surface of the protein,” said one of the authors of the study, Professor Aguts Lalvani.
At the same time, the specialists note the limitations of their research, since it was small.
Earlier Main Preventive URFO, Scientific Head of Society Specialists of Preventive Medicine, Doctor of Medical Sciences Sergey Tokarev and Microbiologist, Scientific Head of Vaccine Vaccine and Serum named after Mechnikov, Academician RAS Vitaly Zverev stated that the hit of new coronavirus strains in the animal environment can lead to Serious virus mutations and new outbreaks of the disease. According to scientists, it is necessary to closely monitor the Omicron option and in humans, and in animals, since a certain supermutant may appear on direct and inverse zoonous transmissions.
