Recruiting studies
- NCT04367857Recruiting
Study of COVID antibody levels in healthcare workers
This study measures how many healthcare workers have COVID antibodies (proof of past infection or immune response). Results may help estimate how widespread COVID exposure has been among hospital staff.

Severe COVID-19 in children in emergency rooms
This trial is studying children who are very sick from COVID-19 or have a related condition called MIS-C. It aims to understand how severe COVID-19 affects children and improve care.
AfulaAges birth–16 years - NCT06183424Recruiting
Brain stimulation for COVID-19 recovery
This trial tests a gentle brain stimulation method called tDCS to help people recover after COVID-19 infection. If you are an adult who recently had COVID-19 and is now testing negative, this study might help improve lingering symptoms.

Unified Protocol for Emotional Health in Long COVID
This study tests a program to help people with Long COVID manage emotional difficulties like depression or anxiety. It combines different therapy approaches into one treatment, which you can receive online from home.
Zaragoza, ZaragozaAges 18 years+ - NCT05866952Recruiting
Breathing and blood-flow testing in long-COVID symptoms
This trial studies how the lungs’ breathing (airflow) and blood flow may be off in people with long-COVID symptoms like tiredness, shortness of breath, or trouble exercising. It may help researchers understand what’s driving symptoms and what kinds of abnormalities could be targeted.
Boston, MassachusettsAges 18–99 - NCT05379556Recruiting
Study for long COVID sexual and reproductive symptoms
This study is looking at people who have recovered from COVID-19 but still have ongoing (long COVID) sexual, reproductive, or related symptoms. Researchers want to learn about these lingering problems and what may help, based on your answers and study procedures.
Naples, ItalyAges 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+ - NCT05242159Recruiting
COVID-19 antibody study in hospitalized patients
This research study examines a specific type of antibody (anti-annexin A2) that may develop during COVID-19 infection. By studying hospitalized COVID-19 patients, researchers hope to understand whether these antibodies are common and what role they might play in COVID-19 illness.
AmiensAges 18 years+ - NCT04474301Recruiting
Quality of life check for people with melanoma during COVID-19
This study looks at how people with melanoma are feeling during the COVID-19 pandemic, including quality of life. You may be asked to share information through surveys or study contact so the researchers can understand needs and concerns.
Houston, TexasAges Any age - NCT06452095Recruiting
Hyperbaric oxygen therapy for long COVID brain fog
This trial tests if hyperbaric oxygen therapy (breathing pure oxygen in a pressurized chamber) helps with long COVID symptoms, especially brain fog and thinking problems. It may be an option if you have had lingering symptoms for at least 2 months and can travel to one of the study sites.
Toronto, OntarioAges 18 years+ - NCT05387304Recruiting
Follow-up study for people with COVID infection in Shanghai
This study follows people in Shanghai who have tested positive for the COVID virus, even if they have no symptoms yet. It helps doctors understand what happens after infection and in people who later get a diagnosis.
ShanghaiAges Any age - NCT05308537Recruiting
Mindful compassion program for nurses feeling emotionally exhausted
This study tests whether a mindful compassion training program can reduce psychological distress in nurses who feel emotionally drained. It targets nurses working on COVID-19 hospital units and compares the program to a wait-and-see group.
Verona, ItaliaAges 25–65 - NCT06599658RecruitingPhase 2
COVID-19 booster and flu vaccine timing for people with weak immune systems
This study tests the best timing for a COVID-19 booster and flu shot in people with weakened immune systems, such as organ transplant recipients, people living with HIV, or those with certain autoimmune conditions. It aims to help patients get better protection from both vaccines.
Montreal, QuebecAges 18 years+ - NCT04582903Recruiting
Send-in sample collection study for immune response to respiratory viruses
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.
Rockville, MarylandAges 1 day–99 years - NCT06441955RecruitingPhase 4
Long Covid prevention and health support trial
This trial tests a care program designed to help people who continue to have symptoms after recovering from COVID-19. It aims to prevent long-term health problems and improve well-being.

Adaptive trial for severe pneumonia care in intensive care
This study tests ways to improve treatment for adults with severe pneumonia that lands them in the ICU, adjusting the plan as results come in. It may help your care team find better treatments for lung infection and breathing/heart support needs.
Jacksonville, FloridaAges 18 years+ - NCT06168032Recruiting
COVID-19 vaccine for lung cancer patients
