Childhood vaccines remain one of the most effective tools in modern medicine, yet vaccine hesitancy is rising, and vaccination rates are falling. The typical response from public health has been to provide more data and scientific facts. But facts alone rarely change behavior.
This report argues that the core challenge is not simply misinformation—it’s misunderstanding the progress parents are trying to make when deciding how best to protect their children’s health.
Today’s parents face an environment saturated with conflicting advice, changing recommendations, and nonstop media and social content. At the same time, human psychology makes it difficult to accurately assess rare risks. In that context, decisions about vaccination can feel less like following medical guidance and more like navigating uncertainty about a child’s safety.
Using the Jobs to Be Done framework, this report reframes vaccine hesitancy as a problem of unmet needs rather than irrational behavior. Parents aren’t rejecting vaccines because they don’t care about health—they’re trying to protect their children in a confusing information environment.
The implication for vaccine communication and public health messaging is clear: messaging must evolve. Instead of focusing primarily on the risks of the shot, leaders should emphasize the protection vaccines provide—the shield. To help practitioners act on this shift, the report also includes practical visual examples—such as risk comparisons and benefit framing—that health care providers and communicators can adapt directly in their own outreach.
Reversing vaccine hesitancy requires a shift in mindset: sell the shield, not the shot.
