Summary

This study gave 239 healthy adults the yellow fever vaccine to learn how the immune system reacts to a real viral infection. The vaccine is safe and effective, making it a good model for studying immune responses. Participants were followed for up to one year to measure their T cell responses. The goal was to better understand immunity, not to test a new treatment.
