Abstract

In a community outbreak of hepatitis A (person-to-person transmission) the efficacy of immune serum globulin prophylaxis among patients'family members was between 87% and 98%. Immune serum globulin efficacy was determined by means of a formula used previously to measure live-virus vaccine efficacy in epidemics.
