Magnesium shots may help avoid steroid during certain immune health issues
This trial studies whether giving a magnesium injection can replace (or avoid) steroids during treatment around times of vaccine, a viral infection, or immune system weakness. It targets adults with long-term (chronic) pain who already receive injection-based treatments and can reliably track symptoms.
Surrey, British ColumbiaAges 20–99 - NCT05553743Recruiting
Study of donated breast milk and how it affects child health

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.
