Alexander Butenko, a virologist at Russia's Gamaleya National Research Center for Epidemiology and Microbiology, compared immunity after vaccination and disease.
This was reported by RT. According to the expert, in both cases the mechanism of immunity is the same both after the vaccine and in any form of the disease. However, antibody levels are higher after the Sputnik V vaccine. "People acquire immunity after experiencing any form of the disease (asymptomatic, mild, moderate) or with the help of a vaccine - the mechanism is the same.
As a result, the population of susceptible and coronavirus-infected people will be limited, ”he said Butenko added that the titer of antibodies is not the only indicator of the presence of immunity, because even if they disappear over time, it does not mean that a person can get sick.
"There is an effect called immunological memory. Contact with a similar pathogen leads to the rapid development of high levels of antibodies, has a protective effect, "he added.
