This study looks at how our bodies fight viruses after getting the yellow fever vaccine. Yellow fever is a dangerous disease spread by mosquitoes, leading to severe health issues and even death. The vaccine helps our immune system by teaching it how to fight off the virus. The study aims to learn more about this immune response to improve future vaccines.
Participants will receive a yellow fever vaccine and may be part of the study for 1 month to 1 year. They will be split into groups based on certain health factors and followed for up to 360 days. Eligible participants are healthy adults aged 18-45 who have not had the yellow fever vaccine before. They must avoid other live vaccines for 30 days before or after getting the yellow fever vaccine. Women must agree to use birth control during the study.
