A. Semashko National Research Institute of Public Health011020243121527052025Copyright © 2025,2025<p>This article is devoted to the methodology of constructing the structure of the index of population adherence to immunisation (vaccination) according to the data of a sociological survey using the author's methodology Algorithm for assessing the level of population ADHERENCE TO VACCINE PROPHYLAXIS. Objective: to propose a methodology for calculating the indicator Index of adherence to immunisation (vaccination), IАI (%) using mathematical modelling.<br />Materials and мethods. The data of sociological survey of respondents using the author's methodology were used in mathematical modelling.<br />Results and discussion. The IАI design includes such indicators as the proportion of respondents with low, medium and high levels of adherence. The IАI can serve as a tool for ranking or clustering the constituent entities of the Russian Federation, medical organisations and their structural subdivisions by the degree of risk of reduced vaccination coverage. The calculation of the IАI indicator is an important indicator of the level of adherence of the population to immunisation.</p>indicatorindexmathematical modellingmethodologysurveyimmunoprophylaxisadherencevaccinationpublic healthIАIпоказательиндексматематическое моделированиеметодикаопросиммунопрофилактикаприверженностьвакцинацияобщественное здоровьеИПИ[Russkikh S.V., Larionov A.V., Vasiliev M.D. Methodical approach to the construction of the index of doctors' confidence in their activities.
