Study Summary

The goal of this clinical trial is to assess the immune response to the yellow fever vaccine 17D in adults with prior 17D vaccination. The main questions this study aims to answer are: * how does prior vaccination affect antibody responses to re-vaccination? * how does prior vaccination affect the immune cell response to re-vaccination? Participants will: * have been previously vaccinated with 17D. * be re-vaccinated with 17D. * provide medical and travel histories. * provide a blood sample prior to vaccination * provide a blood sample approximately every other day for 14 days after vaccination. * provide a blood sample approximately 28 days after vaccination. * complete a daily diary of symptoms following vaccination for 14 days. * report any additional symptoms after 14 days.
