Achieving the required level of herd immunity against a new coronavirus infection (COVID-19) in order to protect the population is an urgent issue in preventive and practical medicine around the world. Herd immunity is an indirect indicator of protection against COVID-19 disease and is made up of the immunity of individuals in a particular group. Epidemiological monitoring of the structure, formation, and dynamics of herd immunity will make it possible to correctly and timely adjust approaches to anti-epidemic measures, both in individual risk groups, in particular among medical workers, and in society as a whole. The required level of herd immunity against a new coronavirus infection can be achieved naturally, after a disease, or artificially, through mass immunization of the population. To date, vaccination is the safest, most effective, and most cost-effective method. Serological research methods (detection of IgG) indicate the effectiveness
of vaccination — the formation of post-vaccination immunity or a past disease. Determining the period of time at which a stable antibody titer is determined, as well as their level, is essential for predicting morbidity.
