Background: A worldwide vaccination program is the chosen strategy against the COVID-19 pandemic. Vaccine hesitancy however, forms a threat because vaccine uptake is voluntary in most countries. Care-professionals of people with intellectual disabilities are exposed to greater risks than other healthcare workers due to the vulnerable group they attend to and the assisted-living facilities in which they often work. Little is still known of the reasons for vaccine hesitancy in this specific group in contrast to those of other healthcare workers. Objective: To provide insight in the intentions and attitudes on COVID-vaccination of healthcare workers, including those who care for people with intellectual disabilities, by means of a scoping review. Methods: The databases that were searched for papers are CINAHL, APA PsycArticles, APA PsycInfo, Web of Science, Semantic Scolar, Prospero, Outbreak Science, Cochrane and Scopus. The search was broadened to healthcare workers in general because only two papers were found on those caring for people with intellectual disabilities. A total of 26 papers were identified concerning the vaccine intentions of 43,199 healthcare workers worldwide. Data were gathered both quantitively and qualitatively. The papers were analysed for all themes regarding vaccine willingness and vaccine hesitancy.Results: The themes that came to light included: percentages of vaccine willingness, predictors of willingness differentiated by 11 sub-themes (mainly profession, age, gender and past vaccine behaviour), attitudes of willingness and hesitancy differentiated by 19 sub-themes (perceived COVID treat and protecting others for willingness, concerns on vaccine safety and efficacy for hesitancy), sources of vaccination information, contextual factors and changes in COVID-19 vaccine acceptance over time and finally, future strategies for interventions. Conclusions: There was overlap in the percentages of vaccination, predictors of vaccine willingness and the attitudes of vaccine willingness and hesitancy between healthcare workers and those caring for people with intellectual disabilities. Vaccine safety and efficacy are the most prominent concerns with regard to vaccine hesitancy. Therefore, future strategies for interventions should address vaccine safety and efficacy. Furthermore, interventions are recommended to be interactive in order to facilitate exchange. Discussion groups that are able to address specific concerns and personal experiences, show to be effective in addressing vaccine hesitancy. Accurate information can also be made more accessible to target groups by promoting videos on social media platforms. Hence, further research is necessary to specify more precisely the attitudes of healthcare workers caring for people with intellectual disabilities and in more countries worldwide.
