The degree of sensitivity to varying dilutions of a poison ivy antigen was established by patch tests in seven individuals. Administration of the live, attenuated measles virus vaccine (Schwarz) to this small group of subjects resulted in a temporary reduction of sensitivity, most marked (33% of control values) between the third and sixth weeks postimmunization. At nine weeks, the sensitivity was returning to preimmunization levels. Five control subjects showed no change in their degree of sensitivity.
