Ethics and immunization policy: Promoting dialogue to sustain consensus

The societal consensus that has supported the United States' universal childhood immunization programs for the past 50 years shows signs of eroding. This article proposes a systematic approach to evaluate immunization policy options. Through a unifying framework that combines epidemiologic, economic, and ethical concerns, this approach promotes a clearer understanding of underlying issues and inherent tradeoffs between alternative policies. Such a systematic examination of policy options could facilitate the public dialogue necessary to continually recreate a broad consensus on immunization practices and enable us to choose policies most in accord with our fundamental values.
