从美国一个具有全国代表性的小组中招募受访者。在一项两波研究中，至少有一名17岁或以下儿童的1759名父母（88%符合入选标准）完成了两波研究。首先，测量儿童健康状况和父母对疫苗的态度。与会者要求提供关于任何疫苗延迟或被拒绝的信息、疫苗的重要性以及对卫生专业人员和机构的信任程度。在第二波中，受访者被随机分配接受控制信息或四种支持疫苗信息之一。第一份包括科学证据，使用与美国疾病控制和预防中心（CDC）网站上类似的语言揭穿了MMR疫苗和自闭症之间的联系;第二份根据CDC疫苗信息声明介绍了与MMR相关的疾病和不良疫苗事件的信息;第三份使用了母亲对住院儿子麻疹发作的描述，也是从CDC网站上获取的;第四张是患病儿童的照片。控制信息包括有关喂养鸟类的信息。
MethodsRespondents were recruited from a nationally representative panel in the USA. In a two-wave study, 1759 parents (88% of those meeting the inclusion criteria) of at least one child aged 17 years or less completed both waves. In the first, child health status and parent vaccine attitudes were measured. Information was sought about any delayed or declined vaccines, the importance of vaccines and how much trust was placed in health professionals and institutions. In wave 2, respondents were randomly assigned to receive a control message or one of four pro-vaccine messages. The first comprised scientific evidence debunking the link between MMR vaccine and autism using similar language to that on the US Centers for Disease Control and Prevention (CDC) website; the second presented information about the diseases and adverse vaccine events associated with MMR based on the CDC vaccine information statement; the third used a mother's description, also taken from the CDC website, of her hospitalised son's measles episode; and the fourth comprised pictures of children with the diseases. The control message comprised information about feeding birds.
