Counteracting misinformation on childhood vaccines remains a priority for public health in industrialized countries. Previous research showed that misinformation-induced vaccine hesitancy particularly concerns very highly or very lowly educated parents, and, especially in Europe, specific groups of immigrants. Misinformation framing directly targets specific sub-population of parents by exploiting different cognitive biases, and specific concerns based on cultural norms: this project aims at testing the effectiveness of similar framing techniques applied to positive information on the HPV vaccine by conducting a Randomized Controlled Trial in Stockholm, Sweden. It randomizes emotionally and scientifically/statistically framed information addressing the specific concerns reported by previous literature.
