Analysis of clinical enquiries received by five COVID-19 vaccination centres in the UK.

The aim of this study was to explore the nature of clinical enquiries received by UK vaccination centres during the early stages in the roll-out of the COVID-19 vaccination programme. Four centres were situated in acute hospitals and one centre was in a designated public site. Data were collected for eight consecutive weeks between January and February 2021. The hospital centres administered a total of 28 995 doses of the Pfizer BioNTech vaccine, receiving 806 enquiries (1 enquiry per 36 vaccinations, 2.7%). The public centre administered 29 167 doses of AstraZeneca vaccine, receiving 439 enquiries (1 enquiry per 66 vaccinations, 1.5%). Combined enquiry rate was 2.1%. The most common enquiries were related to allergies (44%), compatibility with other medicine (22%) and immunosuppression (16%). These were the topics of clinical guidance that were subject to regular change. Public health programmes implementing novel therapies should ensure the provision of sufficient enquiry answering capacity.
