Assessing the acceptability of COVID-19 vaccine and its booster dose.

Background And Objective: Coronavirus disease of 2019 (COVID-19) vaccinations are essential to control the pandemic and prevent severe COVID-19 infections. This study aims to assess the acceptability of the COVID-19 vaccine and the factors that impact the intention to take the COVID-19 vaccine and its booster dose.

Methods: A cross-sectional study was conducted in Saudi Arabia and Jordan. The study used a self-administered web-based survey (questionnaire) for data collection that was distributed via social media platforms from May 2022 to July 2022.

Results: In this study, among 518 participants, 54.4% had already received two doses of the COVID-19 vaccine, and out of the participants who didn't receive the booster dose, 19.9% declared a definite willingness to receive it, while 42% had already taken a booster dose, which indicated good acceptance. After adjustment for significant background characteristics, a significant association between the country and receiving the COVID-19 vaccine, the intention to get the vaccine, and infection with COVID-19 were found, in addition to a significant association between the country and the participants' opinion that electronic applications helped them to follow their vaccine schedule were found (p < .001). Also, the results showed that participants' attitudes were significantly associated with educational level and age groups (p ≤ .001, p = .032, respectively). There was a significant association between the intention to receive the vaccine booster dose and the country (p < .001). The Saudi participants were willing to get the booster dose seven times more than the Jordanians, furthermore, there was a significant association between taking the vaccine booster dose in the country, as well as age group, working in the medical field, previous COVID-19 infection, and the intention to vaccinate the children (p < .001, p = .030, .031, .025, < .001, respectively).

Conclusion: Overall, our results emphasize a positive response and a positive attitude toward COVID-19 vaccination. In addition, define the groups to be targeted with effective communication regarding the COVID-19 vaccine and its booster dose.
