Table 2. Odds ratios for willing to vaccinate for a 5% increase in population vaccination rate by country and odds ratios based on multivariable model including age, who completed the survey and vaccination status (up-to-date or not based on schedule in the country)

Country	OR (95% CI)*	p value	Adjusted OR (95% CI)**	p value
Single dose
Canada	0.82 (0.63, 1.07)	.15	0.96 (0.91, 1.01)	.12
Israel	1.03 (0.95, 1.12)	.47	1.01 (0.99, 1.02)	.49
United States	1.24 (0.99, 1.56)	.07	1.04 (1.00, 1.09)	.08
Two doses
Canada ***	-	-	-	-
Israel	1.00 (0.99, 1.02)	.75	1.00 (0.99, 1.02)	.66
United States	1.07 (0.99, 1.16)	.09	1.07 (0.99, 1.15)	.11

*Estimated from model including week and vaccinate rate. Odds ratios are per 5% increase in population rate of vaccine.

**Further adjusted for age, who completed the survey and child vaccination status (up-to-date schedule vs not up-to-date).

***Could not be computed due to small cell size.
