Vaccination is key in controlling influenza pandemics. Ways of identifying determinants that influence the decision to be vaccinated need to be understood in order to optimize vaccination rates. Therefore, this study aimed to predict intention to be vaccinated against swine flu in priority groups in the UK. An extension of the Theory of Planned Behaviour (TPB) provided the theoretical framework for the study.
The study population consisted of 134 adults from the UK who were in vaccination priority groups, either because they were healthcare professionals or in 'other' vaccination priority groups (e.g. due to having a chronic illness, being pregnant). Data were collected from 30 October 2009 (just after the swine flu vaccine became available in the UK) until 31 December 2009. The main outcome of interest was intention to be vaccinated against swine flu.
Overall, intention was not high. Healthcare professionals were less likely to intend to be vaccinated compared with other priority groups. The theoretical framework was a powerful predictor of intention, explaining 70% of the variance in intention. The most important parts of the model were the demographic variables and original TPB which explained 66% of the variance in intention, with other variables (extended TPB/Health Belief Model) accounting for an extra 4% of the variance in intention. This is in contrast to results from the general population.
The study results provide a useful framework on which to base future interventions for improving uptake of pandemic flu vaccination. These interventions need to be targeted at specific groups given the different results of the priority groups compared with the general population.
接种疫苗是控制流感大流行的关键。为了优化疫苗接种率，需要了解影响接种决策的决定因素。因此，本研究旨在预测英国优先群体接种猪流感疫苗的意愿。计划行为理论（TPB）的扩展为该研究提供了理论框架。
研究人群包括来自英国的 134 名处于疫苗接种优先群体的成年人，他们要么是医疗保健专业人员，要么属于“其他”疫苗接种优先群体（例如，由于患有慢性疾病或怀孕）。数据收集于 2009 年 10 月 30 日（在英国提供猪流感疫苗后不久）至 2009 年 12 月 31 日。主要研究结果是接种猪流感疫苗的意愿。
总体而言，接种意愿不高。与其他优先群体相比，医疗保健专业人员接种疫苗的意愿较低。理论框架是预测意愿的有力指标，解释了意愿 70%的方差。该模型最重要的部分是人口统计学变量和原始 TPB，它们解释了意愿 66%的方差，而其他变量（扩展 TPB/健康信念模型）则解释了意愿 4%的方差。这与一般人群的结果形成对比。
研究结果为改善大流行性流感疫苗接种提供了一个有用的框架。鉴于优先群体与一般人群的结果不同，这些干预措施需要针对特定群体。
