Exploring the psychological drivers and impact of public health communications on vaccination beliefs of minority ethnic groups

行为的心理驱动因素有助于解释为什么个人会从事保护性和危险的健康行为，并为促进行为改变的战略提供信息。最近的证据表明，一些少数民族群体接种COVID-19疫苗的意愿较低。鉴于少数族裔群体的COVID-19发病率、发病率和死亡率较高，这一点令人相当担忧。英国少数民族对疫苗犹豫不决的原因证据有限，但这可能与疫苗安全性/有效性的信念和对正规服务的不信任问题以及实际障碍（如获取）有关。这项研究将涉及三波深入访谈和焦点小组，对象是伦敦和伯明翰的少数族裔社区成员和组织，以了解（i）接种疫苗的具体障碍和促进因素，（ii）COVID-19和疫苗接种风险认知随时间的变化，（iii）建立和维持社区对疫苗接种计划的支持所面临的挑战，及（iv）公共卫生运动对疫苗接种意愿的影响。我们还将使用行为科学框架来评估整个英国的国家和地方运动。这将促进快速发展以证据为基础的，理论上知情的，量身定制的健康信息，这对英国大规模疫苗接种计划的成功至关重要。它还将支持持续的社区参与，这对优化公共卫生成果至关重要。

Psychological drivers of behaviour can help explain why individuals engage in protective and risky health behaviours and inform strategies to promote behaviour change. Recent evidence indicates some minority ethnic groups have lower intentions to receive a COVID-19 vaccine. This is of considerable concern given higher COVID-19 incidence, morbidity, and mortality among minority ethnic groups. There is limited evidence of the reasons underpinning vaccine hesitancy in minority ethnic groups in the UK, but it is potentially linked to beliefs about vaccine safety/efficacy and issues of mistrust towards formal services, as well as practical barriers such as access. This study will involve three waves of in-depth interviews and focus groups with minority ethnic community members and organisations in London and Birmingham to understand (i) specific barriers and facilitators of vaccine uptake, (ii) changes in COVID-19 and vaccination risk perceptions over time, (iii) challenges for building and sustaining community support for vaccination programmes, and (iv) the impact of public health campaigns on vaccination intention. We will also use a behavioural science framework to evaluate national and local campaigns across the UK. This will facilitate the rapid development of evidence-based, theoretically informed, tailored health messages that are critical for the success of the UK mass vaccination programme. It will also support the sustained community engagement that is crucial for optimising public health outcomes.
