It is time to improve the acceptance of COVID‐19 vaccines among people with chronic diseases: A systematic review and meta‐analysis

Abstract

AbstractThis study aims to investigated COVID‐19 vaccine acceptance among people with chronic diseases and the factors correlating with their vaccination hesitancy. The articles were searched in PubMed, Ovid, EMBASE, and web of science databases between December 2019 and October 2022. Cross‐sectional studies, including the acceptance of the COVID‐19 vaccine by patients with chronic diseases (≥18 years old), were included in this study. The outcomes included the proportion and 95% confidence interval (95% CI) of chronic disease patients willing to be vaccinated and the odds ratio (OR) and 95% CI of correlating factors. The source of heterogeneity was analyzed through meta‐regression and subgroup analysis. We included 31 studies involving 57 875 patients with chronic disease. The overall COVID‐19 vaccine acceptance among patients with chronic disease was 0.65 (95% CI, 0.59–0.72). The acceptance among the elderly patients was 0.53 (95% CI, 0.26–0.80). South America had the highest COVID‐19 vaccine acceptance rate and Asia the lowest, while on a country level, the United Kingdom had the highest acceptance rate among patients with chronic diseases. People with rheumatic immune diseases had the lowest rate of COVID‐19 vaccine acceptance. Concerns about vaccine safety had a statistically different effect on acceptance. Overall, the health systems ought to focus on educating specific groups of individuals on the benefits of COVID‐19 vaccination and addressing safety concerns.
