ABSTRACT
Background: COVID-19 vaccine booster dose hesitancy amongst the Saudi Arabia population is a concern. The objectives of the study were to explore the Saudi public's willingness to receive a COVID-19 vaccine booster dose and identify the factors affecting their willingness. Methods: From December 2021 to March 2022, an online cross-sectional survey using an anonymous, structured, and self-administered questionnaire was conducted among members of the Saudi public aged ≥18 years who did not receive a COVID-19 vaccine booster dose. Results: Of the 2101 respondents, 86.8% expressed a willingness to receive a COVID-19 vaccine booster dose. Multiple logistic regression analysis showed that age (18 to 25 years) (adjusted odds ratio [aOR] = 2.54;95% confidence interval [95% CI] = 1.14-5.74), being single (aOR = 2.85;95% Cl = 1.42-5.72), and prior receipt of an influenza vaccine (aOR = 2.45;95% Cl = 1.80-3.34) were significantly associated with participants' willingness to receive the COVID-19 vaccine booster dose. Having a bachelor's degree or above (aOR = 0.95;95% CI = 0.81-0.99) and not following COVID-19 news (aOR = 0.70;95% CI = 0.52-0.89) were associated with a significant likelihood of having no intention to receive the COVID-19 vaccine boosters. Conclusions: Most Saudi people were willing to have the COVID-19 vaccine booster dose, with age and prior influenza vaccination as the predictors;paradoxically, a university-level qualification was a barrier.
ABSTRACT
Backgroundand objectives: Although several vaccines have been produced and administered around the world, new SARS-CoV-2 worsened the COVID-19 infection risk and impacted the initial vaccine dosage effectiveness. Based on studies indicating that the third and fourth COVID-19 vaccine doses significantly reduced COVID-19 transmission, Saudi Arabia has been administering COVID-19 booster vaccine doses to its citizens. The purpose of this study was to evaluate the uptake of the COVID-19 vaccine booster in relation to the socio-demographic characteristics and other associated factors among the Saudi population. Materials and Methods: This study was an online analytical cross-sectional study using a self-administered questionnaire. Pearson Chi-square test and multiple logistic regression analyses were used to determine factors associated with the uptake of COVID-19 booster dose vaccines. Results: A total of 2332 responded to our study. Overall, 527 (22.6%) participants had received a booster dose. An age of 55 and above (aOR: 5.415; 95% CI: 2.719-10.783), Eastern region (aOR: 2.513; 95% CI: 1.566-4.033), history of influenza vaccination at annual intervals (aOR: 2.387; 95% CI: 1.730-3.293), the first dose of Moderna vaccine (aOR: 1.324; 95% CI: 1.160-1.510), and cancer (aOR: 2.161; 95% CI: 1.218-3.879) were independent factors most associated with a higher uptake of the COVID-19 vaccine booster dose. In contrast, the second dose of Moderna vaccine (aOR: 0.794; 95% CI: 0.683-0.922), AstraZeneca vaccine (aOR: 0.691; 95% CI: 0.509-0.939), strong symptoms from side effects after the second dose of the COVID-19 vaccine (aOR: 0.615; 95% CI: 0.404-0.935) were independent factors most associated with a lower uptake of the COVID-19 vaccine booster dose. Conclusions: Our findings indicate low COVID-19 vaccine booster uptake. This necessitates the need for strategies to address discouraging factors of the COVID-19 vaccine booster dose uptake and engage the Saudi population to raise awareness about the importance of the booster dose.
