Figure. Public Health Consequences and Public Sector Costs of Childhood Measles in the United States With Increasing Prevalence of Vaccine Hesitancy.

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).
