| Summary: | <h4>Introduction</h4>Influenza vaccination is a critical public health measure, especially amidst the challenges of the COVID-19 pandemic. This study uses Epic's Cosmos database to analyze influenza vaccination trends across demographic groups in the United States, examining the effects of the COVID-19 pandemic and "vaccine fatigue" on influenza vaccination rates.<h4>Methods</h4>This retrospective cross-sectional study analyzes influenza vaccination rates pre- (1 May 2018-31 May 2019), peri- (1 May 2020-31 May 2021), and post-COVID-19 (1 May 2023-31 May 2024). A two-proportion z-test and Cohen's h test were calculated to assess statistical significance.<h4>Results</h4>Influenza vaccination rates increased peri-COVID (+1.99% point change, h = 0.04, p < 0.001) and decreased post-COVID (-6.41% point change, h = 0.14, p < 0.001) relative to pre-COVID. The largest changes were observed in the following groups: 5-18 year olds (-13.92% point change, h = 0.31, p < 0.001), 19-26 year olds (-9.91% point change, h = 0.25, p < 0.001), American Indian or Alaska Native (-8.11% point change, h = 0.18, p < 0.001), Other Races (-7.36% point change, h = 0.17, p < 0.001), White (-6.89% point change, h = 0.15, p < 0.001), and the South U.S. census region (-7.21% point change, h = 0.17, p < 0.001).<h4>Conclusion</h4>Post-pandemic influenza vaccination compliance decreased relative to pre-pandemic, especially among younger age groups, certain racial groups, and in the southern U.S. These findings suggest that the COVID-19 pandemic negatively impacted influenza vaccination compliance. While overall trends aligned with publicly available data, absolute counts may be under-reported within Epic due to incomplete documentation of vaccine administrations outside of Epic-affiliated systems. |
