Scientists: not everyone develops immunity to coronavirus

Scientists: not everyone develops immunity to coronavirus
A group of doctors in Russia is studying the effect of coronavirus on human immunity. Doctors are trying to find out whether it is possible to get COVID-19 again and how the body of an already ill person will react to the virus.

According to "Rossiyskaya Gazeta", a whole group of doctors is currently working on these and other issues. The group is supervised by Anton Yershov, MD, professor of pathophysiology at Sechenov First Moscow State Medical University. According to him, immunity is not developed to a specific strain of the virus, but to the key links of the virus - antigens. These are the parts that traditionally do not mutate.

Moreover, if the antigens do not change, then the immunity can be lifelong. If, as with the flu virus, a new strain appears every year or two, then the immunity will be seasonal.

As for the coronavirus, if it manifests itself easily or is completely asymptomatic, the body may not notice the virus, which means that immunity will not form. If the disease is severe, then the body under the influence of a virus may simply not be able to cope with the load, and immunity will not work out. Therefore, to create a stable immunity, you need to be ill with a moderate severity coronavirus. Resistance to a new disease can persist for about two years, but so far these data are approximate - too little time has passed to get acquainted with this virus.
