The interventional odds ratio of causal factors that have statistically significant estimated causal effects (at the 5% level) on vaccine intention. The bold text in the y-axis labels indicates the reference level of a given variable, and the error bars are the 95% confidence interval of the odds ratio estimate. The results suggest that making people believe that it is their social responsibility to get vaccinated to protect others, triggering anticipated regret for not taking the vaccine, making people believe that the majority of their community are taking the vaccine, and discouraging the belief that vaccines will be unsafe have the largest effect in increasing vaccine intention from low to high.
