Background In the UK, it is acknowledged that ethnic minority communities have lower vaccination uptake rates compared with their White ethnic counterparts . It is additionally recognised that the UK Muslim community represents diverse ethnicities, which is reflected through their places of worship, namely mosques . Given the current pandemic and the rollout of the COVID-19 Vaccination campaign, mosques, in their capacity as community organisations, have been involved in health promotion initiatives such as webinars . The objective of this project was to support and improve COVID-19 Vaccine related health promotion activities being delivered by mosques in the UK city of Leeds by using a rapidly administered KAP survey . Methods A short survey was developed, reviewed for appropriateness by relevant mosque leaders, and distributed electronically to 2 mosque congregations . Analysis involved cumulative average scores for key domains with adjustment for key demographics, as well as a review of engagement preferences . Findings were fed back during an engagement webinar hosted by one of the mosques . Results There were a total of 151 participants, majority were male (95), between the ages of 31-50 (88) and of Asian ethnicity (102). Average Knowledge, Attitude and Practice scores for participants from Leeds Grand Mosque were 67,69 and 74% respectively, with participants from Leeds Makkah Mosque scoring 65 , 62 and 67% respectively . Female participants as well as those aged less than 30 years scored poorer across all domains compared with the group average . The most important sources of information in relation to the vaccine were considered to be General Practitioners (GP) and National Health Service (NHS) or Government Websites . Conclusions A KAP survey is a useful tool to develop insights on community perspectives to the COVID-19 Vaccine, and can be rapidly deployed through community organisations such as mosques . Survey findings can then be used to improve the nature of health promotion, community engagement and service delivery in relation to mosques and their congregations . Adapting the survey for other groups and communities, as well as scaling up the partnership-based approaches to survey administration would support the development of multi-component strategies to address vaccine concerns and uptake.
