The line indicates the predicted number of annual measles cases in US children (ages 2-11 years) and the associated public sector costs across a range of prevalences for vaccine hesitancy (ie, nonmedical exemptions). The shaded area provides the 90% prediction interval. The vertical dashed line indicates the predicted annual measles cases in children for present day (2% prevalence of vaccine hesitancy). The datapoints represent the observed number of annual cases in recent years. We estimated the consequence of increasing national nonmedical exemptions from 2% to 10% prevalence, and the removal of nonmedical exemptions (0% prevalence).
