Problems of vaccine prevention of whooping cough among the indigenous peoples of the north of Russia on the example of Nenets, living in the territory of the Vorkuta Municipal District

The Nenets are one of the indigenous small — numbered peoples of the North of Russia, leading a predominantly nomadic lifestyle, which determines the difficulties in organizing vaccination work. The aim is to determine the level of coverage of pertussis vaccinations among the child population and identify key factors affecting the level of pertussis immunization among the indigenous peoples of the north. According to the results of a descriptive analysis of the medical records of minor Nenets registered in the territory of the Vorkuta Municipal District, it was found that the coverage of pertussis vaccinations for children of indigenous smallnumbered peoples of the north was 31.9 %, which is significantly lower than the recommended figure of 95 %. Among the main reasons for the lack of vaccinations are late registration in medical organizations (at the age of 4 years and older) and parents' refusal to vaccinate. In addition, in some cases, representatives of the study group lacked documentary evidence of previous vaccinations, which made it significantly difficult to determine their immune status. An important factor in the insufficient coverage of preventive vaccinations against whooping cough by medical organizations is that the national calendar of preventive vaccinations does not regulate the immunization against this infection of persons over 4 years old. In order to motivate the Nenets to vaccinate, taking into account the established factors, it is necessary to strengthen sanitary and educational work in the territories where the traditional routes of movement of the indigenous small peoples of the north are located.
