Observations on the incidence of brucellosis as influenced by the use of strain 19 on cattle of various ages under controlled exptl. conditions, as well as in commercial dairy herds, are reported and discussed. It is concluded that, while far from being an ideal vaccine, strain 19 "is the only product at present that has been used on thousands of animals with any degree of satisfaction.".
