Rubella Susceptibility and Immunization in a University Population: Experience, Strategy, and Policy

Abstract Despite the availability of a safe and effective vaccine, rubella continues to occur in the United States. In recent years 70% of all cases have occurred in college aged individuals. Since 1978 the University of Rochester has required all entering students to have either rubella immunization or rubella serology. Compliance with this requirement has been excellent and has resulted in an increase in the rubella immunization rate from 52% to 71 %. Of those obtaining serology, the overall susceptibility rate (HI titer < 1:16) was 18%. Less than half of susceptible women accepted immunization, and few susceptible men sought immunization. College entry is a logical time to define an individual's rubella status.
