Johns Hopkins Center for Immunization Research

Johns Hopkins Center for Immunization Research The CIR facilitates the development of new vaccines against infectious diseases of global importance.

Since its founding by Dr. Mary Lou Clements-Mann in 1985, the Center for Immunization Research has been dedicated to the advancement of vaccine research for infectious diseases. The center partners with the US National Institutes of Health, Department of Defense as well as private sector sponsors to conduct phase I, phase II and phase III clinical trials for infectious agents like COVID-19, RSV, D

engue, ETEC, Ebola, Zika, Malaria, HMPV, West Nile, Avian Flu, HIV and HPV. CIR faculty and staff have traveled to developing countries in Africa to conduct GCP trainings and continues to travel to countries in South America and Asia to assist other researchers in the proper conduct of clinical vaccine trials. In addition to teaching and mentoring future research leaders at Johns Hopkins University, CIR faculty help to develop local and global vaccine policies by sharing their expertise in vaccine development and by serving on local, national and international committees related to vaccine research and development.

GI expert Dr. Kawsar Talaat's best advice if you develop diarrhea during the Cyclospora outbreak: "If your diarrhea persists for more than a couple days, go see your doctor. If the diarrhea goes away and comes back, that's another sign of a potential Cyclospora infection. And again, go see your doctor."

CDC confirms nearly 7,000 Cyclospora cases in 34 states — nearly 7x last year's count. Lettuce under investigation. What to know and what to do.

The Johns Hopkins CIR is looking for healthy volunteers to participate in an outpatient C. difficile Vaccine study. The purpose of this study is to test an investigational vaccine to see if it can prevent severe diarrhea, reduce how sick people get, and lower the need for medical care or antibiotics in adults 65 years of age and older. If you are 65 years of age or older and have taken antibiotics for at least 48 hours in the last 3 months, or have been hospitalized at least once or had 2 ER visits in the last year, or have had 10 or more healthcare visits in the last year, you may be eligible to participate. The study will last up to 3 and a half years and will include:

Up to 5 in-person visits over the course of the study including 2 vaccination visits
3 phone visits
Twice monthly e-diaries
Eligible people will be compensated for completing study procedures.
