Abstract
Using the yearly standard data supply and data of some representative epidemiological investigations, the present authors studied the impact of the BCG vaccination program on tuberculosis in children during the last 20 years in Hungary. Considering the incidence of active tuberculosis among vaccinated and unvaccinated children according to age as well as the rate of vaccination in the various age groups, authors point out that: [1] the BCG vaccination program proved to be effective during the entire period of investigation; [2] prevalence of bacillary TB had a marked influence on the incidence of the disease, both in vaccinated and unvaccinated children; [3] the impact of the BCG-vaccination program on the problem of childhood tuberculosis had been determined by the percentage of those vaccinated; and finally [4] the relatively high frequency of disease in the higher age groups (15 to 19-year-olds) indicates that the TB problem still exists and continuation of the various TB control methods is therefore justified.
