The one I know of is in Germany, and I only know of it through an acquaintance who is involved in the study. They're now looking for people for Phases 2 and 3.

The one I know of is in Germany, and I only know of it through an acquaintance who is involved in the study. They're now looking for people for Phases 2 and 3. The job-ad for potential participants doesn't mention anything about COVID, though. I'm assuming this is either due to legal reasons, or something along the lines of "we want people to go into this unbiased". In any case, the wording is pretty general, something along the lines of "looking for participants in a clinical study for vaccinations. Applicants must not have contracted covid19 before".
