After adjusting for sociodemographics, health behaviors, and chronic disease diagnoses, receipt of influenza vaccination was significantly associated with recent ILI, with vaccine recipients being more likely to report ILI (aOR 01.50, 95% CI: 1.01Á2.24). Persons who are underweight (BMIB18.5, compared with normal weight) (aOR 03.21, 95% CI: 1.19Á8.65), and those diagnosed with asthma (aOR 02.45, 95% CI: 1.65Á3.62), coronary heart disease (aOR 01.77, 95% CI: 1.17Á2.65), and stroke (aOR 0 1.75, 95% CI: 1.07Á2.87) were also more likely to report ILI.
