The results of complications monitoring of BCG in Sakha Republic (Yakutia)

Abstract

Results of monitoring for complications to BCG vaccine in children in Sakha Republic (Yakutia) are presented. Incidence, structure and nature of complications to vaccines against tuberculosis infection were analyzed; causes of complications were determined. The study established that complications develop most often to BCG vaccine, and rarer to BCG-M vaccine. Lymphadenitis was the prevailing diagnosis in the clinical structure of complications. Severe forms of complications were registered more frequently in children under 3 years of age. Complications in children immunized at pediatric polyclinics or rural first aid posts were mostly due to wrong administration technique. Main causes for complication development were: perinatal pathology, underestimation of counterindications, infectious or virus diseases in postvaccinal period, faults in vaccine administration technique.
