CHARACTERISTICS OF HERD IMMUNITY AGAINST INFLUENZA VIRUSES DURING PERIOD PRECEDING THE EPIDEMIC SEASON OF YEARS 2021-2022 IN THE KHABAROVSK KRAI
Abstract
Evaluation of herd immunity of healthy population of Khabarovsk city against relevant strains of influenza viruses during period preceding the epidemic season was performed. The lowest protection with specific immunoglobulins was revealed against virus strain A/Cambodia /е826360/2020/H3N2/. Mentioned viral strain circulation was revealed during 3rd – 4th quarters of the year 2021. Antigen structure of new A/H3N2/ variant differs from known strains of A/H3N2/. This fact allows us to assume that the new strain can overcome specific herd immunity that population acquired during previous diseases.
