This study looks at how well the flu shot works in healthy people. The flu shot is a vaccine made from a killed flu virus that helps your body fight the flu. Your body makes special defenses called antibodies that help stop you from getting sick. In this study, healthy adults will get a flu shot and have their blood and bone marrow checked several times over a year to see how their immune system responds.
**Key Points**:
- The study lasts up to 1 year for each participant.
- Participants will visit Emory University for sample collections at different times.
- There is no compensation mentioned for participating.
To join, you must be a healthy adult who can agree to participate, and you can't be pregnant or nursing. If you join, your samples will be labeled with a special code to keep your information private. You can also choose whether your samples can be used for future research. This study aims to help make better flu vaccines in the future. If you’re interested, you can contact the study team to see if you’re eligible.
