The general director of the contract research company, Nikolai Kryuchkov, named three options in which a person may not get sick when meeting with a coronavirus infection. The site of "Komsomolskaya Pravda" informs about it .
According to him, first of all, a person must have a strong innate immunity.
"With a relatively small viral" dose ", such immunity will work at the level of the upper respiratory tract and prevent infection from penetrating further into the body," said Kryuchkov.
Also, according to the expert, a person can have a good immune response.
"This is possible, as a rule, in people who have had seasonal coronaviruses, conventionally" ordinary "colds. In this case, their bodies may retain strong antibodies or immune T-memory cells left over from previous meetings with seasonal coronaviruses," he said ...
And the third case, according to the specialist, is possible when a person, although infected with COVID-19, but the immune response acts in the usual way, without inadequate reactions.
Earlier, American and Chinese experts found antibodies to SARS-CoV-2 in the breast milk of women who had undergone coronavirus. Researchers believe that breast milk helps the infant resist the pathogen. According to experts, it can be used for preventive purposes to ensure the protection of adults.
In addition, researchers from the University Hospital in Cologne and the German Center for Infection Research have isolated 28 antibodies that are believed to neutralize COVID-19. The study says the antibodies identified by the experts bind to the pathogen's protein.
Further, they prevent the penetration of the virus into healthy cells. Together with their Israeli colleagues, German specialists studied over four thousand specific B-cells of blood taken from 12 patients who had had a coronavirus infection.
