Objectives: This study aims to identify basic data for improving the vaccination rate by examining the relationship between age-specific demographic and socioeconomic characteristics and influenza vaccination for adults aged 19 to under 64 using the 7th National Health and Nutrition Examination Survey. Methods: 13,104 adults aged 19 to 64 years were selected as participants using the 7th National Health and Nutrition Examination Survey (2016-2018), and the elderly 65 years and older were excluded from the analysis as subjects for free national influenza vaccination. Data analysis was performed using SPSS Statistics 23.0 program. Results: The vaccination rate of women was higher than that of men in the three groups, and there were differences according to marital status for those 49 and occupation by occupation in the group under 40. It was found that there was a difference in the vaccination rate according to the presence of disease, education level, and economic activity status. Conclusions: To increase the influenza vaccination rate, it is necessary to manage the variables that affect influenza vaccination in each of the age groups.
