About this study
This trial is testing how well older adults respond to different influenza vaccines over time. Participants will receive three flu vaccines annually for three years, and blood samples will be collected to understand the immune response. The goal is to learn more about why some people don't get as much protection from the flu vaccine.
Based on ClinicalTrials.gov records.
