Help End Infectious Diseases
Healthy volunteers are essential to ending infectious diseases one day sooner. Whether you are thinking about taking part in medical research or have already volunteered in a study, joining our community helps your contribution go further.
When you sign up, we may keep you informed about meaningful opportunities to take part in research, to help improve the experience of healthy volunteers, and to raise awareness of the vital role they play in research.
1Day Sooner is an independent advocacy group that supports and represents healthy volunteers in infectious disease research. Joining our list does not sign you up for any medical study. We do not run studies, and we do not share your personal information with research teams unless you ask us to.
We only use your details to stay in touch with you, and you can unsubscribe at any time. You can also visit our Recruiting Challenge Studies page to see a non-exhaustive list of studies that are currently looking for volunteers. If you choose to enter a screening process for any of these studies, let us know by emailing volunteer@1daysooner.org.

“I took the plunge and got infected with norovirus to help better understand the disease. To me, it was a relatively simple request: my health, temporarily, in return for scientific advancement.”
Thomas Smiley, Cincinnati, USA
Volunteer
Norovirus GII.4/CIN-3 characterization challenge, 2022
“Shigella causes dysentery, which I can tell you from personal experience feels terrible. I volunteered to be infected to help test a vaccine — I got sick so one day others won’t. It was 100% worth it (and earning a few thousand dollars was nice, too)!”
Jake Eberts, Washington, D.C., USA
Volunteer
Shigella flexneri 2a vaccine challenge, 2022
“Participating in a challenge study was a great way to support research in a different way that I hope can provide a broad clinical impact and improve global health outcomes.”
Dominique Meyers, Baltimore, USA
Volunteer
Shigella flexneri 2a vaccine challenge, 2022
“Nobody wants to get sick (especially with infectious diseases like dysentery!) but I’m hopeful that by people like me volunteering for human challenge studies, medical advances can be made to help protect those most vulnerable.”
Mallory Admire, Baltimore, USA
Volunteer
Shigella flexneri 2a vaccine challenge, 2022
