Impact of the intervention on the vaccination rates odds ratio associated to baseline and completed stages

Vaccine	Population	Baseline (Stage A) Odds Ratio (95% CI)	Stage C Completers Odds Ratio (95% CI)	p Value
Influenza	>65 years	1.98 (1.93–2.03)	2.27 (2.22–2.33)	<0.0001*
	High-risk	1.56 (1.51–1.61)	1.70 (1.65–1.76)	<0.0001*
Pneumonia	>65 years	3.16 (3.07–3.25)	3.43 (3.34–3.53)	<0.0001*
	High-risk	1.70 (1.65–1.75)	1.77 (1.72–1.83)	NS

*statistically significant by Breslow-Day test for homogeneity of the odds ratio (p < 0.05); CI = confidence interval; NS = not significant
