Intent vaccinate lowest Taiwan, highest India, Indonesia, China. Across all countries, associated 1.72 times higher odds intent (95% CI: 1.46, 2.02) 2.13 1.70, 2.67), compared less case. Perceived mediate 25% 18%, 31%, P<0.0001), 16% 12%, 19%, P<0.0001). Seriousness could relate intention against COVID-19.
