title: [Prevention of tuberculosis today].
abstract: After a summary of main defences to prevent tubercular disease, Author refers that only 0,5% of 159,204 BCG-vaccinated subjects at his Institute contracted tuberculosis. Other data confirm that the rôle of an healthy environment is important to prevent the disease, also without BCG intervention and that BCG alone can defend from tuberculosis also without the influence of an healthy environment. A risk environment reduces the BCG effectiveness, but not so significantly. Then the BCG vaccination showed itself an useful means of preventing tuberculosis that today is still indispensable as first antitubercular protection.
