Cyclic Regularities of the Covid-19 Spread and Vaccination Effect on Its Further Reduction

Abstract

The patterns of periodic occurrence of infectious diseases pandemics over the past twenty years and their impact on the economy and society are studied in this paper. The analysis of the spread of the COVID-19 coronavirus pandemic during the last 1.5 years in the global context is carried out. The impact of vaccination on the reduction of the coronavirus pandemic in different countries and regions of the world has been analyzed. It is noted that regardless of the region of the world, the risks of disease recurrence do not disappear even after achieving collective immunity. The impact of vaccination on the further spread of the COVID-19 pandemic has been studied and its likely mitigation in different countries and regions of the world has been predicted. This aspect of the study aims to identify vaccination trends and, on their basis, predict the approximate time horizons of the COVID-19 pandemic in Ukraine and other countries.
