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

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.

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.

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.

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.

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.
