Recruiting studies
- NCT04899765RecruitingPhase 4
Measles and BCG shots for moms and toddlers
This trial tests whether giving measles and BCG vaccines to mothers and their children after the child turns 12 months is safe and helpful. It specifically looks at women who are not pregnant and meet several health and study-area requirements.
Bissau, Bissau CodexAges 15–35 - NCT06023056Recruiting
Hepatitis B vaccine after newborn surgery
This trial tests whether giving the hepatitis B vaccine to full-term newborns who had multiple stomach or intestine surgeries is safe and works well. It aims to protect these babies from hepatitis B infection.
Chongqing, Chongqing MunicipalityAges Any age - NCT05212792Recruiting
Study genes after COVID vaccine side effects
This study looks at genetic information to better understand why some people develop serious side effects after a COVID-19 vaccine, such as GBS, blood clotting with low platelets (VITT/TTS), or heart inflammation (myocarditis/pericarditis). Your information may help researchers learn who is at higher risk and improve future safety.
Vancouver, British ColumbiaAges 5–99 - NCT04834869Recruiting
Track safety after COVID-19 vaccination in adults
This study follows adults who have already received a COVID-19 vaccine to monitor side effects and safety over time. Your participation helps researchers understand how the vaccine affects different people who are at higher risk due to their work.
Philadelphia, PennsylvaniaAges 18 years+ - NCT06067555RecruitingEarly Phase 1
Flu vaccine study for healthy adults
This study tests a flu vaccine given just under the skin (intradermal) to see how well it works. It may be a good option if you are a healthy young adult.
New Haven, ConnecticutAges 18–40 - NCT07636044Recruiting
Shingles Vaccine Response in Lupus Patients
This study tests how well the shingles vaccine (Shingrix) works in people with lupus who take immune-suppressing medications. Researchers want to understand if the vaccine provides good protection in lupus patients, since their immune systems work differently.
SeoulAges 50 years+ - NCT07107516RecruitingPhase 1
Testing an oral cholera vaccine in healthy adults
This study tests an oral cholera vaccine called PanChol in healthy adults. The goal is to see if it's safe and how the body responds. It may help protect against cholera, a serious diarrheal illness.
Lusaka, Lusaka ProvinceAges 18–55 - NCT05923333Recruiting
Breastfed infants of HIV-exposed mothers get a probiotic
This study gives a specific probiotic (from B. infantis) to babies born without HIV to see if it can improve the baby’s early immune health. It focuses on babies who are HIV-exposed because their mother has HIV and plans to exclusively breastfeed for the first 6 months.

Common questions
- Are there clinical trials for vaccination reaction?
- Yes. Clin2 currently lists 8 recruiting vaccination reaction 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 reaction 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 reaction 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.
