Study of immune memory after yellow fever vaccination
Part of Immune system & allergy, Infections clinical trials.
This study looks at how your immune system “remembers” the yellow fever vaccine over time. It may help researchers understand long-term immune protection and how it varies between people.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You can understand the study and sign consent
- You must be 18–45 at the time of your yellow fever vaccine, or 55 or older
- You have proof you received a yellow fever vaccine (a yellow card or medical record)
- You should not have had any vaccines in the 30 days before the study visit
- You cannot take medicines that strongly weaken the immune system
- You must not be pregnant

This study gathers safety and antibody information from women who received their first yellow fever vaccine either during pregnancy or outside of pregnancy. It aims to better understand how the vaccine affects pregnant women and their babies.
This study checks how long your body’s protection signals last after a vaccine. It may help researchers understand which vaccines give longer-lasting immune responses and who may need boosters.
This study looks at how your body's immune system responds to the yellow fever vaccine. It may help researchers understand how well the vaccine protects people.
This trial studies how well the yellow fever vaccine “17D” stimulates the immune system (the body’s germ-fighting response) in adults who were vaccinated with 17D years ago. It may help researchers understand whether a prior vaccination still provides protection and how strong the immune response is.
This study looks at how well the body’s protection against yellow fever lasts 10 years after the first vaccine. It compares people living with HIV (who are on stable treatment) with people who are HIV negative, to learn whether immunity stays strong over time.
This study examines special immune cells that live in your skin to understand how they work. Researchers will take small skin samples to learn more about your body's natural defenses, which could help develop better vaccines in the future.
