Abstract
The article presents the features of the epidemic process of COVID‑19 in the Russian Federation for the period from March 2020 to July 2022. It has been established that the dynamics of the incidence of a new coronavirus infection is characterized by periods of growth and decline in morbidity of varying intensity and duration, which coincides with the appearance and circulation among the population of new variants of the SARS-CoV‑2 virus and the presence of susceptible individuals, as well as with the seasonality characteristic of infections with airborne transmission, preventive measures. It has been established that the adult able-bodied population is more susceptible to the disease, and persons aged 65 years and older are a special risk group for mortality. As a result of the mathematical analysis, the correlation coefficient between the morbidity of the population and those vaccinated against COVID‑19 in the Russian Federation was 0.31%. The correlation coefficient between mortality and those vaccinated against COVID‑19 was minus 0.01. The results obtained indicate a slight effect of vaccination on morbidity, but at the same time confirm the effect of vaccination on mortality reduction. The collective immunity of the population against the SARS-CoV‑2 virus remains below the recommended level necessary to protect the population and does not significantly affect the epidemic process.
