Study how COVID immunity affects reinfection risk
Part of Infections, Lungs & breathing clinical trials.
This study looks at how well COVID-19 protection (immune barrier) holds up over time and how likely people are to get reinfected. It may help researchers understand who is more at risk after prior infection and why.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You can join follow-up visits and check-ins for about 48 weeks
- You (or the study contact) are sure you have had COVID-19 before
- You clearly remember when you first got COVID-19
- You do not have serious ongoing lung (breathing) diseases that could change symptoms
- You do not have major illnesses that strongly affect the immune system

This study collects sent-in samples to better understand how your immune system responds during a COVID-19–like illness and after you recover. It may help researchers learn why some people get sick and others stay uninfected, and how immune protection works over time.
This study looks at how people’s immune protection after COVID-19 may change over time. It aims to better understand immunity, which could help doctors plan future care and prevention.
This study checks how well your lungs work and how much exercise you can do after you’ve been discharged from the hospital for COVID-19. It also measures blood (serology) results to understand recovery and possible immune response changes over time.
This study looks at what factors may make COVID-19 symptoms or infection effects last after someone has recovered. It also collects certain body samples to better understand why this persistence happens.
This study follows adults who had COVID-19 to learn how the illness can affect health over the long term. It may help researchers understand lasting symptoms and who is at higher risk, which could improve future care.
This study gathers information about healthcare workers (adults) and tracks your past COVID-19 infection and vaccination history. It may help researchers understand how COVID affects healthcare workers and how vaccines relate to infection outcomes.
