This study, called "Flu Infection at UPHS," is looking at how your body's immune system responds to the influenza virus (the flu). Researchers want to understand if your body mostly uses existing immune memory or creates new immune responses when you get the flu. You might be able to join if you are 18 or older and have recently tested positive for the flu within the University of Pennsylvania Health System. The main goal is to see how flu infection affects your neutralizing antibody titers (a measure of your immune protection) against different flu strains over two years. The study plans to enroll up to 50 participants each year. The current recruitment status is unclear.
