疫苗安全怀疑论者通常被认为更有可能自我认同为民主党人（而不是独立人士或共和党人）。然而，最近的研究表明，儿童疫苗错误信息在共和党人中更为常见，或者不受党派识别（PID）的影响。接受疫苗错误信息的党派基础的不确定性很重要，因为它可能使追求支持疫苗的卫生政策的努力复杂化。我的理论是，共和党人应该更有可能支持反疫苗的错误信息，因为他们倾向于对科学专家表达更负面的观点。在六项人口统计学和全国代表性调查中，我发现，虽然很少有美国人认为“反疫苗者”更有可能是共和党人而不是民主党人，但共和党PID与儿童疫苗可能导致自闭症的信念显著相关。与理论预期一致，反专家的态度强烈介导的效果，补充面板分析表明，不太可能是反向因果关系。
Vaccine safety skeptics are often thought to be more likely to self-identify as Democrats (vs. Independents or Republicans). Recent studies, however, suggest that childhood vaccine misinformation is either more common among Republicans, or is uninfluenced by partisan identification (PID). Uncertainty about the partisan underpinnings of vaccine misinformation acceptance is important, as it could complicate efforts to pursue pro-vaccine health policies. I theorize that Republicans should be more likely to endorse anti-vaccine misinformation, as they tend to express more-negative views toward scientific experts. Across six demographically and nationally representative surveys, I find that-while few Americans think that "anti-vaxxers" are more likely to be Republicans than Democrats-Republican PID is significantly associated with the belief that childhood vaccines can cause autism. Consistent with theoretical expectations, effect is strongly mediated by anti-expert attitudes-an effect which supplemental panel analyses suggest is unlikely to be reverse causal.
