Virologists explain why vaccinated people become infected with COVID-19

The likelihood of contracting CORONAVIRUS after vaccination depends on the immune response of the body, which manifests itself individually, as well as on how well the protocols for storing the vaccine were followed, virologists interviewed by RBC believe.

“It is possible to get sick after vaccination, especially in the current situation, when there are strains with increased contagiousness in the population, for example, British, Indian. But the disease will proceed in a weakened form, and serious consequences will be avoided, ”virologist, professor at Moscow State University, DOCTOR of Biology Alexei Agranovsky told RBC.

According to another expert, HEAD of the Laboratory for Especially Dangerous Infections of the Federal Research Center for Fundamental and Translational Medicine (FRC FTM), professor of virology Alexander Chepurnov, the degree to which the conditions for storing the vaccine are strictly observed during delivery also affects.

“Both the development [of the vaccine itself], and all the procedures that are associated with it, and the cold chain upon delivery – all this can play a role with some punctures. If all this is impeccable, then we still have the factor of the individual characteristics of the immune system, ”Chepurnov stated. According to him, it is also important which vaccine is administered to the patient and what are its real properties.
