Impact of a Video-Based Educational Intervention on the Levels of Knowledge and Concerns about COVID-19 Vaccination

Background. The hesitancy to receive the COVID-19 vaccine plays a role in delaying the current global and national COVID-19 management strategies. Evidence has highlighted the importance of examining the public’s concerns and knowledge about COVID-19 vaccines in sustaining public prevention of the further spread of the virus worldwide. This study aimed to assess the impact of a video-based educational session on the Saudi public’s levels of knowledge and concerns about the COVID-19 vaccination. Methods. In a double-blind, randomized posttest-only control group study design, 508 Saudis were randomized to an experimental group (n = 253) and a control group (n = 255). The experimental group was exposed to a video-based educational session, while the control group was not. Then both groups were subjected to a validated questionnaire to assess their level of knowledge and concerns about the vaccine. Results. In comparison to the control group, the experimental group showed a significantly lower proportion of overall high concern (0.4% vs. 5.5%, p < 0.001) and a higher proportion of overall good knowledge (74.2% vs. 55.7%, p < 0.001). After adjustment for possible confounders, the experimental group showed a significantly lower percent mean score of overall concern (45.0% vs. 65.0%, p < 0.001) and a higher percent mean score of overall knowledge (74.2% vs. 55.7%, p < 0.001) than the control group. Conclusions. The video-based educational intervention positively impacted the levels of knowledge and concerns about COVID-19 vaccination among the experimental group. These interventions safeguard against the rumors and misconceptions about COVID-19 vaccinations. Further studies on the impacts of such interventions on vaccine uptake are recommended.
