CI – confidence interval
*Note: The sample had 90 countries and 2200 country-week observations. Vaccine coverage was measured by the number of people received at least one vaccine dose per 10 people in the population. The standard errors were clustered at the country level. The R-squared value was 0.52. The model included country random effects and variables for country characteristics, nonpharmaceutical interventions, and continent indictors described in Table 1.
