To the Editor In a Viewpoint, Mr Gostin1 argued that if more children were vaccinated and exemptions made less accessible, outbreaks like the one that occurred in Disneyland would not happen. I disagree with this conclusion.
The US Centers for Disease Control and Prevention has yet to identify the index case, and 57% of those infected were not children.2
