The structure of complaints about diseases of 28,432 children aged 0 to 14 years was studied, for the period from 2006 to 2019 to a medical organization against the background of vaccination. The data of the medical information system were used. To compare the distributions of values in vaccinated and unvaccinated children, the “copy-pairs” method and the nonparametric Mann-Whitney test were used. It was found that the analysis of data over a long period of time, allows you to identify special effects. Thus, the vaccinations given to children do not lead to a decrease in the number of visits for diseases, but lead to changes in the structure of visits by children in ICD‑10 classes. In unvaccinated children, the proportion of requests for diseases of the genitourinary system, infectious and parasitic diseases is significantly higher than in vaccinated children. Starting from the age of 4 years, the proportion of vaccinated children with diseases of the digestive system is higher than that of unvaccinated children.
