People's intentions to use vaccines are influenced by their beliefs about both the specific vaccine and the disease it prevents. In the absence of firm beliefs about Zika virus (ZIKV), individuals may base their intentions to vaccinate against it on beliefs about other vaccines, and specifically the misbelief that MMR causes autism.
A survey of 3337 Americans, using a random-digit-dialing sample of landline telephone households and cell-phones.
Intentions to use a Zika vaccine were influenced by beliefs about Zika, science in general, and MMR. Intentions were positively influenced by perceived severity of and vulnerability to Zika, as well as belief in science's efficacy. However, intentions were negatively influenced by the belief that MMR causes autism in children.
The misbelief about MMR and autism may reduce people's intentions to use a new Zika vaccine. However, perceptions of severity of and vulnerability to Zika may increase intentions. Implications for science educators and public health officials are discussed.
人们接种疫苗的意愿受到他们对特定疫苗和预防疾病的信念的影响。在对寨卡病毒（ZIKV）没有坚定信念的情况下，个体可能会根据对其他疫苗的信念来决定是否接种寨卡病毒疫苗，特别是错误地认为麻疹、腮腺炎、风疹三联疫苗会导致自闭症。
一项针对 3337 名美国人的调查，使用了随机数字拨号抽样的固定电话家庭和手机样本。
接种寨卡病毒疫苗的意愿受到对寨卡病毒、一般科学和麻疹、腮腺炎、风疹三联疫苗的信念的影响。接种意愿受到对寨卡病毒的严重程度和易感性、对科学有效性的信念的积极影响。然而，接种意愿受到麻疹、腮腺炎、风疹三联疫苗会导致儿童自闭症的信念的负面影响。
麻疹、腮腺炎、风疹三联疫苗与自闭症之间的错误信念可能会降低人们接种新的寨卡病毒疫苗的意愿。然而，对寨卡病毒的严重程度和易感性的认知可能会增加接种意愿。本文讨论了对科学教育者和公共卫生官员的启示。
