Vaccine therapy for breast cancer that has spread to the brain and spinal cord
This trial tests a new type of vaccine (dendritic cells) injected directly into the spinal fluid, combined with either trastuzumab (if your breast cancer is HER2-positive) or nivolumab (if your breast cancer is HER2-negative). The goal is to see if this combination can better control breast cancer that has spread to the lining of the brain and spinal cord.
Tampa, FloridaAges 18 years+ - NCT07680582RecruitingEarly Phase 1
Personalized cancer vaccine after surgery for solid tumors
This trial tests a personalized vaccine designed to train your immune system to fight any remaining cancer cells after surgery or during standard therapy. It is for people with solid tumors who are stable and have no signs of disease getting worse.

Distraction cards vs toy squeezing for kids getting shots
This trial compares using distraction cards or a squeezable toy to help children aged 4–7 feel less pain and fear during a routine vaccination shot.
Mersin, ProvinceAges 4–7 - NCT06463119Recruiting
Vaccine response registry for immune-weakened patients
This study creates a registry to track how people with weakened immune systems respond to vaccines. It helps doctors better understand which vaccines work best for patients like you.
GenevaAges Any age - NCT07651891RecruitingPhase 4
Dog allergy vaccine study for Swedish adults
This study tests an allergy shot (Alutard SQ Dog) for people with moderate to severe dog allergies. It aims to see how well the vaccine works in Swedish medical practices.
Lund, Skåne CountyAges 18–50 - NCT07651761Enrolling by invitation
Vaccine Talk Training for Primary Care Doctors
This study tests whether special training helps primary care doctors have better conversations with patients about flu and COVID-19 vaccines. You may be eligible if you're a patient who visits a participating clinic during the 2026–2027 vaccine season.
Worcester, MassachusettsAges 18 years+ - NCT06137755RecruitingPhase 1
Shingles vaccine study for healthy adults 50-65
This trial tests a new shingles vaccine in healthy adults aged 50 to 65. Shingles can cause a painful rash, and the vaccine aims to prevent it.
Seoul, Eunpyeong-guAges 50–64 - NCT07637630Recruiting

Common questions
- Are there clinical trials for vaccination?
- Yes. Clin2 currently lists 575 recruiting vaccination 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 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 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.
