Note: 6 Respondents who declined to respond to the question “Would you take a COVID-19 vaccine?” were excluded from regression analysis. OR: odds ratio; aOR: adjusted odds ratio. 1 Versus older/existing vaccines. 2 A composite score was computed using six items. Each question had a scale of 0–3, corresponding to low–high vaccine acceptance; the total composite score was then categorized as low (<6), medium (6–12), or high vaccine (>12).
