人们无法根据正确的信息更新他们的记忆可能会产生重要的公共卫生后果，就像疫苗接种选择一样。在本研究中，我们比较了疫苗推广的三种潜在有效策略：一种是将神话与事实相对比，一种是采用事实和图标框，另一种是显示未接种疫苗的患病儿童的图像。自闭症/疫苗联系和疫苗副作用的信念，沿着打算给未来的孩子接种疫苗，在纠正干预后立即和延迟7天后进行评估，以揭示可能的适得其反的效果。结果表明，现有的纠正疫苗错误信息的策略是无效的，而且往往适得其反，导致意想不到的相反效果，加强了对疫苗接种的毫无根据的信念，并减少了接种疫苗的意图。对疫苗研究的影响，错误的信息和建议的进展进行了讨论。
People’s inability to update their memories in light of corrective information may have important public health consequences, as in the case of vaccination choice. In the present study, we compare three potentially effective strategies in vaccine promotion: one contrasting myths vs. facts, one employing fact and icon boxes, and one showing images of non-vaccinated sick children. Beliefs in the autism/vaccines link and in vaccines side effects, along with intention to vaccinate a future child, were evaluated both immediately after the correction intervention and after a 7-day delay to reveal possible backfire effects. Results show that existing strategies to correct vaccine misinformation are ineffective and often backfire, resulting in the unintended opposite effect, reinforcing ill-founded beliefs about vaccination and reducing intentions to vaccinate. The implications for research on vaccines misinformation and recommendations for progress are discussed.
