Abstract
INTRODUCTION: This report uses 2024 National Health Interview Survey (NHIS) data to present the percentage of adults age 65 and older who had an influenza vaccination in the past 12 months and who ever had a pneumonia vaccination, by selected sociodemographic characteristics. Trends in vaccination from 2019 to 2024 are also presented. METHODS: Data from the 2024 NHIS were used for this analysis. Point estimates and corresponding variances for this analysis were calculated using SAS-callable SUDAAN software to account for the complex sample design of NHIS. Differences between percentages were evaluated using two-sided significance tests at the 0.05 level. Linear and quadratic trends by family income were evaluated using orthogonal polynomials in logistic regression. KEY FINDINGS: The percentage of adults age 65 and older who had an influenza vaccine in the past 12 months and also the percentage who ever had a pneumonia vaccine were lower in 2024 compared with 2019. In 2024, 67.1% of older adults had an influenza vaccine in the past 12 months, with vaccination lowest among adults ages 65-74 (62.6%) compared with ages 75-84 (71.9%) and age 85 and older (75.3%). Women were more likely than men to have ever received a pneumonia vaccine, but there were no significant differences by sex for receipt of influenza vaccine.
