Since the outbreak of new coronal pneumonia (COVID-19) in late 2019, more than 600 million people have been diagnosed worldwide, with the United States having the most severe outbreak, with over 95.5 million cases. and 1.05 million deaths, putting local epidemic prevention units under great pressure. However, there are some lucky people. Even if they survive in a high virus environment, they are still not infected. They are the legendary “chosen people”, but in reality they may not only be lucky, but have genes and people. Different!
American publication “WiredHe reports that scientists are now trying to unravel the secret that the ‘chosen person’ will not be infected, stating that there is a group of people who clearly have high-density contact with confirmed cases, but will not show any symptoms or even be infected. For example, the husband deals with confirmed cases. Their wives were not infected; they believed that these people were able to avoid the epidemic not only by luck, but also by the hidden genetic key.

For this reason, at the beginning of the epidemic, foreign scientists even formed a team of “Covid Human Genetic Effort” to study the symptoms of new coronary pneumonia caused by genetic differences. András Spaan, a clinical microbiologist at Rockefeller University in New York, published an article in Nature Immunology, hoping to find these “chosen people” from around the world to conduct experiments and further find the answer.
Mara, Professor of Viral Immunology, University of London·Mala Maini and colleagues collected blood from several health care workers who were considered high-risk individuals but had not been infected; Mala compared blood samples from other pre-pandemic populations and found 10 among medical staff, up toCross-reactive T lymphocytes have appeared in the trachea of 6 people, which may constitute a second line of defense against invasive foreign substances.
Mara has simply described that she thinks these thingsT lymphocytes are like an automatic car. They can change gears quickly when they encounter a virus invasion. People without T lymphocytes are self-manual. They need some reaction time to adapt the body to the resistance to the virus. This is probably the best choice. People will not be infected, or the reason for the low probability of infection.
CurrentlyMara is working with researchers at the University of Oxford to develop a vaccine they hope will induce in the mucous membranes of the respiratory tractT lymphocytes appear and it is believed that this vaccine can not only protect itselfSars-CoV-2 is more resistant to various coronaviruses, preventing the continuous evolution of the virus and causing vaccine failure; under ideal circumstances, Mara believes the vaccine can prevent the mutual infection of zoonotic diseases.
