COVID-19 pregnancy medicine registry for expecting or recent mothers

PET scan study of immune activity after COVID-19
This Phase 2 study uses a special PET scan to look at how active your immune system is after a recent COVID-19 infection. The goal is to understand what the immune response looks like and whether this imaging approach could help guide care.
San Francisco, CaliforniaAges 18 years+ - NCT04705766Enrolling by invitation
Study kidney injury after recent COVID infection
This study looks at how COVID can affect the kidneys soon after infection. You may be able to participate if you recently tested positive for COVID and have not had kidney replacement treatments.

Study flu vaccine immunity in people after COVID-19
This study looks at how well your immune system (your body’s infection-fighting system) responds to a flu vaccine after you’ve had COVID-19. It may help doctors understand why some people have different protection after vaccines.
Palo Alto, CaliforniaAges 9–64 - NCT04278404Recruiting
Drug safety study for children already on certain medicines

What taking part in a covid-19 study involves
A screening visit first
Before anything else, the study team checks whether you fit — usually a visit with some tests. You can stop at any point, and screening is typically free.
Care at a nearby site
Study visits happen at a clinic or hospital taking part. Many studies cover the cost of the study treatment and related visits, and some reimburse travel.
You stay in control
Taking part is voluntary and you can leave a study at any time, for any reason, without affecting your regular care.
The team decides eligibility
Our fit check is a helpful first read, not a decision. The study team makes the final call after reviewing your health history.

Common questions
- Are there covid-19 clinical trials in California?
- Yes. We're currently tracking 30 recruiting covid-19 studies with a site in California, each rewritten in plain language so you can see what it's testing and who it's for.
- How do I find out if I qualify for a covid-19 study in California?
- Each study lists its eligibility rules — age, diagnosis, prior treatments. On every trial page we explain these in plain language and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Do I have to live in California to take part?
- Not necessarily. These studies have a site in California, but eligibility is about your health, not your address — some people travel to take part, and a few studies reimburse travel. The study team can tell you what's required.
- Does it cost anything to join a covid-19 trial?
- Using Clin2 is always free. Many trials cover the study treatment and related visits; some reimburse travel. The study team explains exactly what's covered before you decide.
