Volunteers needed for inpatient study at CIR

The Johns Hopkins Center for Immunization Research is looking for healthy volunteers to participate in an inpatient CampETEC challenge study. The purpose of the study is to learn more about the safety and tolerability of an experimental dairy-based product (CampETEC) designed to prevent diarrhea caused by Campylobacter and enterotoxigenic Escherichia coli (ETEC).

If you are between the ages of 18 and 50, you may be eligible to participate. The study is six months long and requires the following:

  • 2 screening visits
  • 1 inpatient stay lasting 12 days
  • 2 follow-up visits

Eligible people will be compensated up to $3,250. For more information, call 410-955-SAVE (7283) or visit the CIR website.
