Three times as many cases of measles were reported in the United States in 2014 as in 2013. The reemergence of measles has been linked to a dangerous trend: parents refusing vaccinations for their children. Efforts have been made to counter people's antivaccination attitudes by providing scientific evidence refuting vaccination myths, but these interventions have proven ineffective. This study shows that highlighting factual information about the dangers of communicable diseases can positively impact people's attitudes to vaccination. This method outperformed alternative interventions aimed at undercutting vaccination myths.
2014年美国报告的麻疹病例数量是2013年的三倍。麻疹的再度出现与一个危险趋势有关:父母拒绝让孩子接种疫苗。人们已努力通过提供反驳疫苗接种谣言的科学证据来对抗人们的反疫苗态度,但这些干预措施已被证明无效。这项研究表明,突出有关传染病危险性的事实信息能够对人们的疫苗接种态度产生积极影响。这种方法比旨在削弱疫苗接种谣言的其他干预措施更有效。
