This study is a collaboration between The Jackson Laboratory for Genomic Medicine (JAX) in Farmington, CT and UConn Health in Farmington, CT. All recruitment, enrollment, clinical data, and sample collection will occur at the UConn Center on Aging (COA), at UConn Health in Farmington, CT under the direction of Dr. George Kuchel, Professor of Medicine and Director of the UConn COA. Coded samples collected at Visits 1-17 will be securely transported to the Jackson Laboratory for Genomic Medicine (JAX), located on the UConn Health campus, for processing, storage, sequencing, and analysis. Dr. Duygu Ucar will oversee sample management and sample and data analysis per protocol. In this study, a total of sixty (60) healthy adults aged 65 years and older who have had no history of confirmed COVID-19 and have not received influenza vaccination for the approaching influenza season will be enrolled in the study and vaccinated with influenza vaccines approved by the U.S Food and Drug Administration (FDA) and recommended by the Centers for Disease Control and Prevention (CDC) for individuals ≥65 years. All participants receive influenza vaccine during the 2022-23, 2023-24, and 2024-25 influenza seasons. Participants will receive Fluzone® Quadrivalent High-Dose vaccine during the 2022-23 and 2024-25 flu seasons and FLUAD® Quadrivalent during the 2023-24 flu season. Blood samples will be collected from the participants at each of the seventeen study visits over three years. Nasal swab and stool samples will also be collected from participants at 7 time-points across the study period. The study is not designed to assess safety or tolerability of the influenza vaccines administered as part of this proposed study. By performing comprehensive profiling of their blood antibodies and immune cells over time, we will be able to associate specific age-related immune alterations with vaccine responder or non-responder status, thus allowing us to pinpoint biological pathways that can be targeted to enhance vaccine efficacy and that can also help us to progress towards developing a universal influenza vaccine.
