Individuals are susceptible to misinformation, such as the incorrect notion that vaccines cause autism. Despite strong evidence to the contrary, many individuals still believe that childhood vaccinations cause autism (DeStefano et al., 2013; Horne et al., 2015; Jain et al., 2015). Here, we examine the conditions under which this misconception may be eliminated. The current study is a replication of Horne et al. (2015), who found that communicating the risk of diseases targeted by vaccines was more effective than directly correcting misinformation. The findings from this study will provide the general public as well as public health officials with a scientific basis for how to successfully alter attitudes towards vaccines.
