Summary

This trial studies how prior vaccination affects the immune response to the yellow fever vaccine 17D in adults. Participants will provide medical and travel histories, blood samples, and a daily diary of symptoms.

Who is the study for?
Adults aged 20-49 who are in good health and have been previously vaccinated with the yellow fever vaccine (17D) at least 8 years ago. They must be able to follow trial procedures, provide a detailed medical history, and not plan to travel to yellow fever endemic areas during the trial.
What is being tested?
The study is testing how well adults respond to a re-vaccination of the yellow fever vaccine (17D). It looks at antibody responses and immune cell reactions after getting another dose of the same vaccine they received before.
What are the potential side effects?
Participants may experience symptoms similar to those from their initial vaccination, which can include mild fever, soreness at injection site, or fatigue. A daily diary will help track any side effects for two weeks post-vaccination.
