The 2014-15 Disneyland measles outbreak that began at the California theme park in December 2014 sparked an international conversation regarding measles, vaccine hesitancy, and vaccine policies. The outbreak capped a year with the highest number of measles cases reported in two decades and came amidst increasing trends in nonmedical vaccine exemptions in California and elsewhere. Because of its sensational story line and spread among unvaccinated populations, the outbreak received a high level of media coverage that focused on vaccine hesitancy as a primary driver of the outbreak. This media coverage and the ostensible public support for vaccines that followed led some to hypothesize that the outbreak might have a "Disneyland effect," or a positive influence on the uptake of pediatric measles vaccine. This article reviews the facts of the outbreak and its context, and explores the evidence for the Disneyland outbreak causing an influence on U.S. pediatric vaccine-related beliefs and behaviors.
2014-15 年迪士尼乐园麻疹疫情始于 2014 年 12 月的加利福尼亚主题公园，引发了国际社会对麻疹、疫苗犹豫和疫苗政策的讨论。此次疫情爆发正值 20 年来报告麻疹病例数量最高的一年，也是加利福尼亚州和其他地方非医学疫苗豁免趋势不断上升的时候。由于其耸人听闻的故事情节和在未接种疫苗人群中的传播，该疫情受到了高度的媒体关注，重点关注疫苗犹豫作为疫情的主要驱动因素。这种媒体报道以及随后公众对疫苗的明显支持，使得一些人推测疫情可能产生了“迪士尼乐园效应”，即对美国儿童麻疹疫苗接种产生了积极影响。本文回顾了疫情的事实及其背景，并探讨了迪士尼乐园疫情是否对美国儿科疫苗相关信仰和行为产生影响的证据。
