Materials and methods. The authors analyzed the history of child development and maps of preventive vaccinations of 631 children under 18 months of age to establish the completeness and timeliness of vaccinations against infections, approved by National immunization schedules. The authors analyzed the reasons for the lack of vaccinations and violations of the start and end of vaccination. To assess the population's attitude to vaccination, a survey of 865 parents and 1325 employees of medical organizations were conducted.
