Relative age-adjusted income deprivation-related inequalities in flu vaccine uptake among older adults (age 65 years plus) stratified by sex—Male results.

Results from Cox proportional hazards models adjusted by age are reported as hazard ratios with 95% confidence intervals. The reference groups are D10 (least deprived areas) and age 65–69 years for each season. The vertical line indicates the onset of the pandemic. (DOCX)</p

SII by income deprivation for age-adjusted flu vaccine uptake inequalities over time.

Age-adjusted estimated difference in vaccine uptake (percentage points) between the least and most income-deprived areas. Estimates shown with 95% CIs. The vertical dashed grey line indicates the onset of the pandemic. Results for preschool (age 2–3 years) and primary school (age 4–9 years) children estimated using IDACI; results for older adults (age 65 years plus) estimated using IDAOPI. CI, confidence interval; IDACI, income deprivation affecting children index; IDAOPI, income deprivation affecting older people index; SII, slope index of inequality.</p

Relative age-adjusted income deprivation-related inequalities in flu vaccine uptake among older adults (age 65 years plus)—Sensitivity analysis excluding adults on the border of age-based vaccine eligibility (i.e., excluding age 64/65 years).

Results from Cox proportional hazards models adjusted by age are reported as hazard ratios with 95% confidence intervals. The reference groups are D10 (least deprived areas) and age 66–69 years for each season. The vertical line indicates the onset of the pandemic. (DOCX)</p
