[The place of the principal antibrucellic vaccines in prophylaxis].

This communication is intended to clarify the conditions and methods of the utilization in France of the antibrucellic vaccines in accordance with regulations covering the prevention of brucellosis in animals. It should be noted that it is only within the framework of the prophylaxis of bovine brucellosis that the problem of the utilization of these vaccines will be investigated. Since the objective is the complete eradication of the disease, measure taken within the framework of the regulations are essentially aimed at eliminating contaminated animals; these are for the most part sanitary measures. However, this type of prophylaxis cannot yet be undertaken simply by the application of the regulations because of the lack of financial support accorded by the State. For this reason, as well as because the high rate of infection in certain regions would make the application of these measures very difficult for the farmers, it seemed necessary to utilize vaccines to ensure protection and to attain, in a preparatory phase, a decrease in the rate of infection.
