Preventing rubella: assessing missed opportunities for immunization

Cases of rubella continue to occur among adults in the United States because 10-20 per cent of persons in this age group remain susceptible. To evaluate the potential preventability of these cases, we present a method for assessing missed opportunities for rubella immunization, based on immunization recommendations of the Immunization Practices Advisory Committee (ACIP) of the US Public Health Service (PHS). Immunization programs faced with limited resources can use analysis of missed opportunities to focus on those gaps in implementation contributing most to the remaining rubella cases.
