Uptake of MMR vaccinations is as low as 60% in some parts of the UK. This poses a serious public health issue. This longitudinal study investigates parental decisions about MMR and single vaccinations. Parents (n=114) rated their perceptions of the benefits and risks of immunisation, and emotion-related variables; and were followed up to ask their final immunisation decision. Analyses demonstrated that parental decisions were explained by emotion-related variables, specifically anticipated responsibility and regret. It was concluded that parents' decisions about MMR are strongly influenced by the idea than harm that occurs as a result of deciding to immunise (commission) is less acceptable than harm that occurs as a result of deciding not to immunise (omission) (known as 'omission bias').
在英国的一些地区，麻疹、腮腺炎和风疹（MMR）疫苗的接种率低至60%。这构成了一个严重的公共卫生问题。这项纵向研究调查了父母关于MMR联合疫苗和单一疫苗接种的决定。114名家长对他们对免疫接种的益处和风险的认知以及与情绪相关的变量进行了评分；并对他们进行随访，询问他们最终的免疫接种决定。分析表明，父母的决定可以由与情绪相关的变量来解释，特别是预期责任和后悔情绪。研究得出的结论是，父母对MMR疫苗的决定受到这样一种观念的强烈影响，即因决定接种疫苗（主动行为）而产生的危害比因决定不接种疫苗（不作为）而产生的危害更不可接受（这被称为“不作为偏误”）。
