The effect of inflammation and damage to lymph node structures on durable protective immunity following vaccination

Are you planning to receive the yellow fever vaccine for upcoming travel? This study may be for you! How well a vaccine works sometimes varies by geography, with good protection in one part of the world and poor protection in others. In this research study, the research team is investigating if this is due to different infections in communities, which could affect parts of the immune system that are needed for a good response to a vaccine. Healthy participants who receive the yellow fever vaccine in Uganda and Minnesota will have their levels of infections (from viruses, bacteria, fungi, parasites, and helminths [a type of parasitic worm]) compared. This will help us learn more about relationships between these infections, how they affect immune systems, and how that affects the body’s response to a vaccine.
