Note. CI = confidence interval; GED = general equivalency diploma; OR = odds ratio from logistic regression with year as continuous independent variable and vaccine uptake (≥ 1 dose) as dependent variable. Adjusted for complex survey design. Estimates weighted with WTFA_SA; logistic regression weighted with WTFA_SA/5. The sample size was n = 10 513.
P values correspond to the Rao–Scott χ2 test for differences in vaccination uptake by subgroup category.
Estimate does not meet National Health Interview Survey standard for reliability or precision.
As defined in the National Health Interview Survey.
*Statistically significant difference (P < .05) compared with previous year’s estimate.
