    Area of Science:

    • Public Health
    • Immunology
    • Epidemiology

    Background:

    • Tuberculosis incidence in Hungary was high before 1959.
    • The BCG vaccination program evolved significantly.
    • Previous BCG strains showed reduced efficacy.

    Purpose of the Study:

    • To evaluate the impact of a resolute BCG vaccination program in Hungary.
    • To analyze tuberculosis incidence trends in children and adults.
    • To inform ongoing BCG policy for effective tuberculosis control.

    Main Methods:

    • Systematic BCG primary and revaccination program implemented since 1959.
    • Use of specific BCG strains (Paris 1102, P1173) with defined dosages.
    • Monitoring of tuberculosis incidence rates in children and adults.

    Main Results:

    • Child tuberculosis incidence dramatically decreased from 250 to 1 per 100,000.
    • Adult tuberculosis rates remained a concern, posing a risk to children.
    • Over 7.8 million vaccinations were administered since 1959.

    Conclusions:

    • The BCG vaccination program significantly reduced childhood tuberculosis in Hungary.
    • Continued compulsory revaccination is crucial for sustained immunity.
    • Policy adjustments in 1983 aimed to bolster immunity in children and adults.
