ЗАКОНОМІРНОСТІ ВПЛИВУ ВАКЦИНАЦІЇ НА ДИНАМІКУ ПОШИРЕННЯ РІЗНИХ ВАРІАНТІВ SARS-COV-2. ДВОРІЧНИЙ АНАЛІЗ

Abstract

The new coronavirus, now known as SARS-CoV-2, has attracted the attention of thousands of scientists around the world. This attention is primarily due to the significant impact of this pathogen on the economic and social aspects of the existence of a large number of people. Rapid and powerful anti-epidemic measures in most countries have led to a slowdown in the pandemic. And with the creation of a number of effective vaccines against SARS-CoV-2, we have learned to counteract its spread in the field of resistance of each individual. Which obviously created an additional selection factor. And according to the classical concept of the host-parasite system, human impact on SARS-CoV-2 theoretically requires appropriate adaptive changes of the latter. In this work, by analyzing the statistical data available in open sources, we try to identify and study the existing patterns of the impact of vaccination on the dynamics of the spread of different SARS-CoV-2 variants for the period from the beginning of the pandemic to November 2021.
