A Prospective Questionnaire-Based Study to Evaluate Factors Affecting the Decision to Receive COVID-19 Vaccination in 267 Patients with Inflammatory Bowel Disease in Poland

BACKGROUND: The aim of the study was to assess the rate of COVID-19 vaccination and the attitudes toward receiving COVID-19 vaccination among patients with inflammatory bowel disease (IBD) in Poland. An important aim of the study was to determine why some people get vaccinated and others refuse to do so. MATERIAL/METHODS: This was a single-center, prospective survey. The study included 267 IBD patients who agreed to complete an anonymous questionnaire comprising 31 questions. RESULTS: We found that 71.2% of the IBD patients had been vaccinated. The history of COVID-19 was associated with a lower vaccination rate (16.9% vs 36.8%; P=0.001), regardless of IBD severity. In the vaccinated group, there were more vaccinated people among household members (90.4% vs 43.4%; p<0.001) and friends (52.9% vs 22.4%; P<0.001). Family safety (71.1%), the desire to avoid COVID-19 (67.9%), social responsibility (60.5%), the desire to return to normal life (51.6%), and faith in vaccination as such (43.2%) were the most common reasons for vaccination. The most common cause of non-vaccination was concern about adverse effects (50.0%), including long-term adverse effects (36.8%), and about the possible exacerbation of gastroenterological disease (34.2%). CONCLUSIONS: IBD patients are more likely to be vaccinated against SARS-CoV-2 than the rest of the population in Poland. Young age, low socioeconomic status, low education, and living in the countryside were factors associated with lower vaccination rates. Family and friends had the greatest influence on the decision to vaccinate, but the influence of the mass media was very small.
