提示：为了测试旨在减少疫苗误解和增加麻疹-腮腺炎-风疹（MMR）疫苗接种率的信息的有效性，方法：基于网络的全国代表性2波调查实验进行了1759父母年龄18岁及以上居住在美国谁有孩子在他们的家庭年龄17岁或以下（2011年6月至7月进行）。父母被随机分配接受4种干预措施中的一种：（1）来自疾病控制和预防中心的解释缺乏MMR导致自闭症的证据的信息;（2）来自疫苗信息声明的关于MMR预防疾病危险的文字信息;（3）患有MMR疫苗预防疾病的儿童的图像;（4）来自疾病控制和预防中心的MMR导致自闭症的信息。（4）一个戏剧性的叙述一个婴儿谁几乎死于麻疹从疾病控制和预防中心的情况说明书;或对照group.RESULTS：没有干预措施增加父母的意图，为未来的孩子接种疫苗。反驳MMR/自闭症联系的说法成功地减少了疫苗导致自闭症的误解，但尽管如此，那些对疫苗态度最不好的父母接种疫苗的意图却减少了。此外，患病儿童的图像增加表达的信念在疫苗/自闭症的联系和一个戏剧性的叙述，一个婴儿在危险中增加自我报告的信念在严重的疫苗副作用。结论：目前的公共卫生沟通疫苗可能是无效的。对于一些家长来说，他们实际上可能会增加误解或降低疫苗接种意愿。试图增加对传染病的关注或纠正有关疫苗的虚假说法，尤其可能适得其反。需要对疫苗宣传进行更多的研究。
OBJECTIVES:To test the effectiveness of messages designed to reduce vaccine misperceptions and increase vaccination rates for measles-mumps-rubella (MMR).METHODS:A Web-based nationally representative 2-wave survey experiment was conducted with 1759 parents age 18 years and older residing in the United States who have children in their household age 17 years or younger (conducted June-July 2011). Parents were randomly assigned to receive 1 of 4 interventions: (1) information explaining the lack of evidence that MMR causes autism from the Centers for Disease Control and Prevention; (2) textual information about the dangers of the diseases prevented by MMR from the Vaccine Information Statement; (3) images of children who have diseases prevented by the MMR vaccine; (4) a dramatic narrative about an infant who almost died of measles from a Centers for Disease Control and Prevention fact sheet; or to a control group.RESULTS:None of the interventions increased parental intent to vaccinate a future child. Refuting claims of an MMR/autism link successfully reduced misperceptions that vaccines cause autism but nonetheless decreased intent to vaccinate among parents who had the least favorable vaccine attitudes. In addition, images of sick children increased expressed belief in a vaccine/autism link and a dramatic narrative about an infant in danger increased self-reported belief in serious vaccine side effects.CONCLUSIONS:Current public health communications about vaccines may not be effective. For some parents, they may actually increase misperceptions or reduce vaccination intention. Attempts to increase concerns about communicable diseases or correct false claims about vaccines may be especially likely to be counterproductive. More study of pro-vaccine messaging is needed.
