High trust countries vaccinate more, and the gap widens.
We plotted a historical trend of vaccine uptake delineated into high and low trust countries. The plot shows clearly that high trust countries have a higher mean vaccine uptake over low trust countries, with the gap widening over time. We regressed vaccine uptake as of April 18, 2021 with trust in EU institutions. A positive coefficient for trust in EU institutions along with a p-value of less than 0.05 clearly indicates a statistically positive relationship.
