This study is a “registry,” meaning it collects medical information about people who develop possible heart inflammation after a COVID-19 vaccine. It may help doctors understand how often this happens and which findings are linked to it.
Ottawa, OntarioAges 5 years+ - NCT04936529RecruitingPhase 2
Vaccine with beta-glucan and GM-CSF for neuroblastoma
This trial is testing whether adding a vaccine to a substance called beta-glucan (which may help the immune system) and a growth factor drug called GM-CSF can help prevent high-risk neuroblastoma from coming back. You would receive these as an injection or IV. The study is for people whose cancer is in remission or has responded well to prior treatment.
New York, New YorkAges Any age - NCT02358187RecruitingPhase 2
Vaccine for children and teens with low-grade brain tumors
This trial tests a peptide vaccine plus a medication called poly-ICLC for people with certain low-grade gliomas that cannot be fully removed. The goal is to help the immune system recognize and attack the tumor.
Pittsburgh, PennsylvaniaAges 1–21 - NCT04669171RecruitingPhase 1/Phase 2
Vaccine treatment for slow-growing lymphoma, alone or combined
This trial tests a new vaccine medicine (EO2463) to treat indolent non-Hodgkin lymphoma (slow-growing lymphoma), either by itself or with other treatment. It may help your immune system recognize and attack lymphoma cells.
Boston, MassachusettsAges 18 years+ - NCT04664556Recruiting
Study of severe pneumococcal infections in children
This study tracks cases of invasive pneumococcal disease (a serious infection) in children and newborns. It may help clinicians better understand how these infections happen and guide future prevention and treatment.
CréteilAges 1 day–18 years - NCT04588402Recruiting
Tests whether HPV vaccination prevents cervical HPV infection in young women
This study looks at whether HPV vaccination lowers the chance of getting HPV in the cervix. It will collect cervical samples and ask questions to see how vaccination affects infection in women in Sikkim, India.
Gangtok, SikkimAges 18–22 - NCT04521764RecruitingPhase 1
Vaccine for Metastatic Breast Cancer
This trial tests a vaccine (MV-s-NAP) that is injected directly into a tumor to stimulate your immune system against breast cancer. It is for people with metastatic breast cancer that has spread despite prior treatments.
Rochester, MinnesotaAges 18 years+ - NCT04486638Recruiting
Dengvaxia pregnancy registry in the US
This registry collects information about people who were pregnant and exposed to the Dengvaxia vaccine during pregnancy, to better understand outcomes after that exposure. It may help future mothers and clinicians by building a clearer safety and health record over time.
San JuanAges Any age - NCT04131413RecruitingPhase 1
HPV vaccine given through the skin for HPV16 cervical disease
This early-phase study tests a vaccine designed to help your immune system fight HPV16, a type of human papillomavirus linked to abnormal cells in the cervix. You may or may not be living with HIV, and the team will check safety and immune response after giving the vaccine in a specific way.
Birmingham, AlabamaAges 19 years+ - NCT04106115RecruitingPhase 1/Phase 2
Durvalumab vaccine trial for high-risk bladder cancer after BCG
This early-phase trial tests durvalumab given with an experimental bladder cancer vaccine to help stop or slow high-risk bladder cancer that did not respond to or cannot be treated with BCG. It also evaluates safety and how well the treatment works in this setting.
CambridgeAges 18 years+ - NCT04128189RecruitingPhase 3
Shingrix vaccine for people waiting for a kidney transplant
This Phase 3 study tests whether the shingles vaccine Shingrix is safe and effective for adults with chronic kidney failure who are on the transplant waiting list. It aims to protect you from shingles while you may be dealing with transplant-related immune changes.
Aurora, ColoradoAges 18–70 - NCT04112355Enrolling by invitation
Tracking children’s immune response after routine vaccinations
This study measures how a child’s immune system responds after standard childhood vaccines, like DTaP-IPV/Hib, pneumococcal, MMR, varicella, flu, and COVID shots. It may help researchers better understand what a “healthy” immune response looks like after vaccination.
Rochester, MinnesotaAges 4 months–21 years - NCT04006808RecruitingPhase 1/Phase 2
Shingles prevention vaccine study for kids with kidney transplants
This study tests whether an investigational shingles (herpes zoster) vaccine is safe and helps prevent shingles in children who have had a kidney transplant. Because these children take medicines to prevent rejection, the study specifically looks at vaccine effects in this higher-risk group.
BrusselsAges 1–17 - NCT03971669RecruitingPhase 4
Blood donor study testing safety of donating in health
This trial studies people who donate blood and checks what happens in your body after donation, focusing on safety and measurements in lab tests. You may be able to join if you are healthy and pass screening labs and health history checks.
Baltimore, MarylandAges 18 years+ - NCT03878121RecruitingPhase 1
Ad4-HIV vaccine study for healthy adults and partners
This Phase 1 study tests whether an experimental HIV vaccine (made from a harmless viral vector) is safe and helps the body build immune defenses. It includes healthy volunteers and, in some groups, their close partners, with careful screening and follow-up visits.
Bethesda, MarylandAges 18–65 - NCT03804944RecruitingPhase 2
Vaccine trial for hormone-positive breast cancer
This Phase 2 study tests an individualized vaccine made from your tumor information to help your immune system fight hormone-positive breast cancer. You may be able to participate if you meet specific hormone-receptor, health, and treatment-timing requirements.
Los Angeles, CaliforniaAges 18–90 - NCT03219450RecruitingPhase 1
Personalized vaccine for early-stage, treatment-free CLL
This Phase 1 study tests a personalized cancer vaccine made from each patient’s CLL (“neoantigens”) plus a medicine called poly-ICLC to help the immune system learn to recognize the cancer. It is designed for people who have CLL but are currently not needing treatment, to see if it’s safe and may help keep the disease under control.
Boston, MassachusettsAges 18 years+ - NCT03017820RecruitingPhase 1
