Use of invitations and reminders are associated with higher levels of Herpes zoster (shingles) vaccination uptake. A cross-sectional survey of general practices in Wales, and ecological analysis of uptake data, 2022

In 2013, shingles vaccination was introduced in Wales as a routine immunisation programme for older adults. Invitation for this vaccination has historically been recommended but not mandated by vaccination policy. We surveyed general practices to investigate if invitations and reminders are associated with higher uptake of shingles vaccine. Using data from general practices, we calculated practice-level shingles vaccine uptake between 01/07/2021 and 31/06/2022 for registered patients aged 70–84 years. We distributed an online survey via email to all general practices in Wales on their use of vaccination invitations and reminders, method of invitations, and characteristics of their vaccination delivery. We used linear regression to calculate coefficients and 95 %CI to measure associations between invitations and vaccine uptake, adjusting for key demographics, with a multi-level component to account for similarities between general practices within the same health board. Survey response rate was 37 % (143/384). Median vaccine uptake for responding general practices was 57 % (IQR 50–68 %) compared to 58 % (IQR 48–68 %) nationally. General practices inviting all eligible patients (n = 95) had a 9 % (95 %CI 6–13 %) higher vaccination uptake compared to those inviting none or some (n = 48, p
