Recruiting studies
- NCT06605755Recruiting
Testing a pentavalent vaccine in 2-month-old babies
This trial tests a combined vaccine that protects against five diseases (diphtheria, tetanus, whooping cough, polio, and Hib) in 2-month-old babies who have already received 4 doses. It aims to check the vaccine's safety and how well it builds immunity.
Nanjing, JiangsuAges 1.6 years–1.8 years - NCT06862102Recruiting
Multiple HPV Infections and Cervical Lesion Risk
This study looks at how having multiple types of HPV virus affects the development of abnormal cervical cells (called CIN). It may help doctors understand why some people are more at risk and could lead to better prevention.
Pavia, PaviaAges 18 years+ - NCT07698600RecruitingPhase 1
Safety test of a new HIV vaccine in adults with or without HIV
This study tests a new RNA-based vaccine called BNT168 to see if it is safe and how the body responds to it. It is for healthy adults with or without HIV, and those with HIV will pause their regular treatment for a while during the study.
Houston, TexasAges 18–50 - NCT07203755RecruitingPhase 1
Combination vaccine for whooping cough, Hib, and meningitis
This trial tests a new combination vaccine that protects against whooping cough, Haemophilus influenzae type b (a cause of meningitis and pneumonia), and several types of meningococcal disease (a cause of meningitis and bloodstream infections). It may help reduce the number of shots needed for children.
Shangqiu, HenanAges 2 months–6 years - NCT07085702RecruitingPhase 1
Testing a new Strep A vaccine in healthy young adults
This study tests a new vaccine designed to protect against Group A Strep bacteria. It will check how safe the vaccine is and how well it boosts your immune system. Healthy young adults between 18 and 25 years old may be eligible.
Botany, New South WalesAges 18–25 - NCT04843111Recruiting
Registry study for pregnancy exposure to MenQuadfi vaccine
This is an observational registry that collects information about pregnant people and their babies when MenQuadfi® (a meningitis vaccine) was given during pregnancy or shortly before pregnancy. It helps researchers understand what happens to women and offspring after this vaccine exposure.
Swiftwater, PennsylvaniaAges Any age - NCT05027776RecruitingPhase 3
HPV vaccine study for healthy girls and young women
This trial studies whether a quadrivalent HPV vaccine is safe and helps the body build protection (immunity) against HPV. It enrolls healthy Chinese females who are not already treated for HPV-related infection.
Mianyang, SichuanAges 9–26 - NCT06129253Recruiting
GLOBE-HPV: Study of HPV in communities
This study is trying to find out how many people in different communities have HPV (human papillomavirus). It involves collecting samples and answering questions to help estimate the global burden of HPV.
DhakaAges 9–50 - NCT06216470RecruitingPhase 2
Testing an antibody treatment for chronic hepatitis B
This study tests a new antibody treatment (VIR-3434) for chronic hepatitis B. It aims to see if the antibody can help your immune system control the virus, potentially allowing you to stop your current antiviral medication later.
Toronto, OntarioAges 18–65 - NCT07286370RecruitingPhase 2
Vaccine study for typhoid and salmonella in infants
This study tests a new vaccine that could protect infants against typhoid fever and a serious type of salmonella. If your baby is healthy and within the age range, they may be eligible to participate.
BanjulAges 1 month–6 months - NCT03354728RecruitingPhase 1/Phase 2
Vaccine trial for children with CMV after stem cell transplant
This trial studies a vaccine designed to help the body fight cytomegalovirus (CMV) in children who test positive for CMV and are about to receive a donor stem cell transplant. If it works, it may reduce CMV-related illness during recovery after transplant.
Duarte, CaliforniaAges 1–21 - NCT06822907RecruitingPhase 4
Testing pneumococcal vaccine during a fever in adults
This trial tests if a pneumococcal vaccine (PCV-20) is safe and works well when given to adults during a fever. It may help protect people with certain health conditions from serious pneumococcal infections.
Saint-Etienne, FranceAges 18–85 - NCT07232706RecruitingPhase 3
RSV prevention in infants with nirsevimab and maternal vaccine
This trial tests giving a medicine called nirsevimab to newborns and a possible vaccine to pregnant mothers to prevent RSV, a serious lung infection in babies. It checks if combining both is safe and works better than nirsevimab alone.
La Roche-sur-YonAges 18 years+ - NCT06059391RecruitingPhase 2
Vaccine for stem cell donors to prevent CMV
This trial tests whether giving a CMV vaccine to stem cell donors can help protect recipients from CMV infection after transplant. It is for adults with specific blood cancers who are CMV-positive and have a matched related donor.
Duarte, CaliforniaAges 18–75 - NCT07204457RecruitingPhase 2/Phase 3
Meningococcal vaccine trial for healthy adults 19 to 55 years old
This trial tests a new meningococcal conjugate vaccine (EG-MCV4) in healthy adults to see how well the body's immune system responds and if it's safe. If you qualify, you'd help researchers learn if this vaccine can prevent meningococcal disease.
SeoulAges 19–55 - NCT06810934RecruitingPhase 1/Phase 2
New COVID-19 vaccine study for those with prior mRNA vaccines
This study tests a new type of COVID-19 vaccine that is designed to train your immune system to make stronger, longer-lasting protection. You may be able to join if you are 40–64, have already had at least two doses of a mRNA COVID-19 vaccine (Pfizer or Moderna) more than 4 months ago, and are generally healthy.
Los Angeles, CaliforniaAges 40–64 - NCT07530198RecruitingPhase 1
HIV DNA vaccine test for people on stable treatment
This study tests a new DNA vaccine (ICVAX) designed to help your immune system better control HIV. You'll receive injections over several months if your HIV is well-controlled with current medications.
Shatin, New TerritoriesAges 18–60 - NCT06928753RecruitingPhase 4
Chikungunya vaccine study in La Réunion
This study is for people who are eligible for the chikungunya vaccine in La Réunion. It looks at how well the vaccine works in real life, if it’s safe, and how your body responds to it.
Saint-DenisAges 18 years+ - NCT01793168Recruiting
Rare disease registry and history study
This study keeps a registry (a structured list) of people with rare diseases and may also track how the condition changes over time. It can help researchers better understand rare illnesses and find gaps in care, which may improve future treatments.

Common questions
- Are there clinical trials for vaccination; infection?
- Yes. Clin2 currently lists 91 recruiting vaccination; infection studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a vaccination; infection trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a vaccination; infection trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
