Misconceptions Drive COVID-19 Vaccine Hesistancy in Individuals with Inflammatory Bowel Disease.

Background: Vaccination is an effective public health measure to combat the SARS-CoV-2 pandemic. However, vaccine "hesitancy" has limited uptake in some, including inflammatory bowel disease (IBD) patients who may have unique concerns influencing uptake.

Aim: The aim of the study is to explore attitudes, concerns, and the influence of different sources of information on COVID-19 vaccine uptake in IBD patients.

Methods: Patients from a specialist IBD clinic at a tertiary hospital in Australia and a national IBD patient society were invited to complete an anonymous online survey regarding COVID-19 vaccination. Demographic characteristics, attitudes towards vaccination, and trust in sources of information were explored. Logistic regression was used to identify variables associated with vaccine uptake.

Results: Of 441 respondents, 93% of respondents had received at least 1 dose of COVID-19 vaccination. Self-perceived risk of being more unwell with COVID-19 infection due to IBD (AOR 5.25, 95% CI 1.96-14.04, p < 0.001) was positively associated with vaccine uptake. Concerns regarding the safety of vaccination in pregnancy (OR 0.22, 95% CI 0.08-0.65, p=0.006) and of causing an IBD flare (OR 0.28, 95% CI 0.10-0.77, p=0.01) were negatively associated with vaccine uptake. In total, 282 (73.7%) responders ranked healthcare workers the most trusted source to obtain information surrounding vaccination.

Conclusion: Vaccine hesitancy in IBD patients is low. Concerns about the safety of vaccination in pregnancy and in causing an IBD flare are both associated with vaccine hesitancy. Healthcare providers play a key role in proactively addressing these misconceptions particularly in the context of emerging virus variants and the availability of boosters.
