Recruiting studies
- NCT06577467Recruiting
Studying leftover virus after covid recovery
This study looks for signs of leftover SARS-CoV-2 virus in people who have fully recovered from COVID-19, including those with ongoing neurological symptoms (like brain fog, fatigue, or nerve pain). It aims to understand why some people have long-lasting symptoms after infection.

NîmesAges 18 years+ - NCT06008860RecruitingPhase 4
Astepro nasal spray for early COVID-19
This trial tests whether Astepro nasal spray can help people with mild or no COVID-19 symptoms recover faster. If you have tested positive and are vaccinated, you may qualify.
Chicago, IllinoisAges 18 years+ - NCT05973084Recruiting
COVID spread study in Malawi households and vaccine recipients
This study tracks how COVID-19 spreads and causes illness in real households in Blantyre, Malawi, and compares groups after infection or vaccination. If you qualify, you’ll do follow-up testing and visits for several months.
Boston, MassachusettsAges 5–75 - NCT05914649Recruiting
Testing long COVID and POTS brain fog symptoms
This study tests how different long-COVID and POTS-related symptoms—especially “brain fog”—show up and improve. It may help researchers better measure symptoms so future treatments can be targeted more effectively.
Calgary, AlbertaAges 18–60 - NCT05566483Recruiting
Study long COVID physiology and cardiopulmonary rehab effects
This study looks at how long COVID affects the body and whether cardiopulmonary rehabilitation improves quality of life and physical function. It may help participants better understand their symptoms and see if a structured rehab program improves daily abilities.
Aurora, ColoradoAges 18 years+ - NCT05656105RecruitingEarly Phase 1
PET scan study of brain inflammation after COVID
This early-phase study uses a special PET scan to look for signs of brain inflammation in people with ongoing (long-term) nervous system symptoms after COVID-19. It may help researchers understand what is driving symptoms and whether this imaging approach can detect inflammation.
Birmingham, AlabamaAges 18–65 - NCT04392401Recruiting
Study immune changes in adults during ICU stay for COVID-19
This study looks at how your immune system responds while you’re in the intensive care unit (ICU) for COVID-19. Researchers will collect samples early in the ICU stay to better understand immune changes during the illness.
BronAges 18 years+ - NCT05384561Recruiting
Training your sense of smell to help after COVID
This trial studies whether structured smell (olfactory) training can improve ongoing smell problems after COVID-19. It may help people whose sense of smell hasn’t fully returned long after the infection.
Trois-Rivières, QuebecAges 18 years+ - NCT05359991Recruiting
Exercise study in children and teens with lung or blood conditions
This study tests how safe and effective a structured exercise program is for children and teens. It also compares results between children with sickle cell disease, cystic fibrosis, and healthy peers (and some teens after COVID-19 infection).
Irvine, CaliforniaAges 10–17 - NCT05141058RecruitingPhase 1
T cell therapy to help prevent COVID-19 after transplant
This Phase 1 trial tests a donated immune-cell treatment (T cells) to help immunocompromised people fight or resist COVID-19 after they recently received a bone marrow or stem cell transplant. It aims to see if the treatment is safe and if it helps the body respond better to the virus.
Washington D.C., District of ColumbiaAges 2–80 - NCT04815096RecruitingPhase 2
PET scan study of immune activity after COVID-19
This Phase 2 study uses a special PET scan to look at how active your immune system is after a recent COVID-19 infection. The goal is to understand what the immune response looks like and whether this imaging approach could help guide care.
San Francisco, CaliforniaAges 18 years+ - NCT04705766Enrolling by invitation
Study kidney injury after recent COVID infection
This study looks at how COVID can affect the kidneys soon after infection. You may be able to participate if you recently tested positive for COVID and have not had kidney replacement treatments.
San Francisco, CaliforniaAges 18 years+ - NCT04429594Recruiting
Study tracking COVID-19 infection rates in the public
This study looks at how often SARS-CoV-2 (the virus that causes COVID-19) infection happens in people who may have been exposed in the community. It may help researchers understand infection rates and patterns in the general population.
NiceAges 18 years+ - NCT04448145Recruiting
Study why COVID lasts after recovery
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.
New York, New YorkAges 7 years+ - NCT07601412Recruiting
Understanding Immune Response to Respiratory Viruses in Older Adults
This study examines how the body's natural defense system (specifically a type of immune protein) responds to common respiratory viruses like flu and cold in older adults. Researchers will analyze nasal samples that are already being collected as part of routine care to better understand why older people sometimes have different immune responses to these infections.
LyonAges 60 years+ - NCT06458504Recruiting
HIV infection and bone marrow health study
This study looks at how HIV infection affects the bone marrow's ability to make blood cells. Researchers will use bone marrow samples already taken from HIV-positive patients and compare them to samples from people without HIV.
Boulogne-BillancourtAges 18 years+ - NCT04424992Recruiting
Observing hospitalized adults with COVID-19 lung infection
This study follows adults who are hospitalized with COVID-19 in the lungs. The goal is to better understand how COVID-19 behaves in the hospital over time.
