Abstract

The article examines the effectiveness of BCG vaccination in children exposed to tuberculosis at home. Two groups of children under 7 years who had tuberculosis contact were analyzed: Group 1 - 117 healthy children and Group 2 - 87 patients with tuberculosis. It was found that in the 1st group there were significantly fewer unvaccinated children - 6.8%, than in the 2nd group 21.8%. BCG vaccination helped to reduce the severity of the process and reduce the epidemic risk of tuberculosis in children (OR = 23.929, 95% CI 2.59; 22.97). In children exposed to drug-sensitive or drug-resistant tuberculosis differences in the proportion of those vaccinated and not vaccinated with BCG were not found in 1st and 2nd groups. А conclusion was made about the protective effect of BCG vaccination in children under 7 years who are household contacts of tuberculosis сases.
