During 2014-2016, 69.2% of all older adults, aged ≥65 years, had received an influenza vaccine in the past 12 months. The percentage of older adults with family income ≥200% poverty level who had received an influenza vaccine in the past 12 months significantly increased from 67.9% during 1999-2001 to 72.2% during 2014-2016. During the same period, the changes from 55.7% to 60.8% among those at the <100% poverty level and from 60.3% to 62.9% for those at the 100% to <200% poverty level were not statistically significant. During both periods, older adults with income ≥200% poverty level were significantly more likely to receive an influenza vaccine compared with those with lower family income.
