Look Again: Research,Uncertainty, and Understanding

Abstract

An outbreak of measles (rubeola) occurred on the Bloomington campus of Indiana University in February 1983, resulting in 179 clinically diagnosed cases. An aggressive, voluntary immunization program followed by the possibility of sanctions against nonimmunized students returning to campus after spring break resulted in 23,000 vaccinations, with other students submitting verifications of previous history of disease or live-vaccine immunization.

The factors that may have contributed to the outbreak were less natural immunity in this age group, absence of school legislation when these individuals were entering school, and use of killed vaccine which did not provide immunity.
