[Specific prevention of tuberculosis in young patients by BCG vaccine].
The efficacy of antituberculous BCG revaccination studied in workers, students and young subjects of the penitentiary labour establishments (PLE) was assessed by the level of tuberculin sensitivity, the presence of a postvaccination skin sign, tuberculosis morbidity and severity of a tuberculosis process. The highest efficacy was achieved in workers and students as a result of systematic revaccination. Tuberculosis morbidity in them was 26.2 and 34.5 per 100,000, respectively. In the PLE contingent it was several times higher because they received revaccination as early as their school years. The postvaccination skin signs were found in 91.8% of workers, 76.4% students and 60.5% young subjects of PLE. In students and workers reactions with an infiltrate size of 5-11 mm were predominant and in the PLE contingent those with an infiltrate of 12 mm and more. Subjects having a skin sign had more benign tuberculosis course. Bacillary excretion was found in 48.9% and in those without a skin sign in 72% of cases (p less than 0.05).
