Arbovirus T cell response study

This study is looking at how viruses like those spread by mosquitoes (arboviruses) affect people in Fiji. If you join, researchers will track your health over time to find better ways to prevent and treat these infections.

This study looks at patients with suspected, probable, or confirmed arbovirus infections (like dengue, chikungunya, or Zika) to understand what factors lead to hospitalization and how severe the illness can be. It may include adults, children, and even newborns if they might have been exposed.

This study examines special immune cells that live in your skin to understand how they work. Researchers will take small skin samples to learn more about your body's natural defenses, which could help develop better vaccines in the future.

This study looks at how a person’s immune system responds after exposure to Ixodes (black-legged) tick bites. It aims to better understand the body’s early immune reaction after tick exposure, using blood tests and small skin samples.

This study aims to understand how people's immune systems respond to viruses that spread from animals to humans (zoonotic viruses). If you have had recent contact with potentially infected animals in Cambodia, your participation can help researchers find ways to detect and prevent future outbreaks.

This trial uses a genetically modified malaria parasite given by mosquito bite to safely test a new vaccine approach in healthy volunteers. If you qualify, you'll help researchers understand how the body defends against malaria.
