Predictors of daily vaccinations at mass vaccination centres

Variable	Risk ratio [95% CI]
Mean daily temperature (°C)	1.06 [1.05–1.06]
Rainfall>20 mm (ref: <20 mm)	0.67 [0.56–0.79]
Snowfall>20 cm (ref: <20 cm)	0.43 [0.33–0.56]
Weekend (ref: weekday)	1.02 [0.97–1.07]

The model accounts for variation between MVC and for daily remaining unvaccinated population (coefficients not shown); model offset: logged daily capacity at each MVCAbbreviations: CI, confidence interval.
