The world health organization calls vaccine hesitancy a top 10 threat to global health. Changing parents beliefs about vaccines is difficult. This novel study examined parental cognitions driving vaccine beliefs. A large national sample of almost 2000 US parents of 3-35 month old children completed an online survey. Parents who perceived their child as highly vulnerable to disease were more likely to be vaccine hesitant. This opens avenues for novel interventions to improve vaccination rate among young children.
