The Relation of Heterophile Immunity to the Incidence of Colds

[摘要] This is a report of a more intensive study of 47 of the 1036 patients reported in a previous article (1). The 47 cases reported in this paper consisted of 30 cases who received the oral vaccine, and 17 cases who were used as controls. The object of this study was to show the relation between the patient's response to the heterophile antigen, and his frequency of colds. These cases were chosen because of the availability of blood samples. An effort was made to distribute the cases who had received the oral immunization between those who had apparently benefited and those who had not. The heterophile titer of the blood sera of the patients was then studied in relation to the distribution of colds in these groups.The vaccine consisted of rough pneumococci (D.R.I.) and streptococci. The pneumococci were high in heterophile antigen. Each capsule contained one hundred billion of each organism.
