Notes. Vaccination: 0 = non-vaccination and 1 = vaccination. Default option: 0 = opt-in and 1 = opt-out. Herd immunity threshold: 0 = 7 out of 10 and 1 = 10 out of 10. Gender: 0 = male and 1 = female. Education: 0 = below bachelor's degree and 1 = bachelor's degree or above. Significance levels: ∗ p < .05, ∗∗ p < .01, and ∗∗∗ p < .001.
