Facts About the CIR

What is the CIR?

The Center for Immunization Research (CIR) is part of the Department of International Health of the Johns Hopkins University Bloomberg School of Public Health. The CIR was established in 1985 by Dr. Mary Lou Clements-Mann.  For more than 25 years, the CIR has provided leadership in the areas of early phase vaccine evaluation and vaccine education efforts. CIR investigators primarily conduct Phase I and II safety, immunogenicity, and efficacy trials of new vaccine candidates. The CIR is also the world leader in training other research professionals to develop the skills and infrastructure needed to design, conduct, and evaluate clinical vaccine trials, with a focus on applied Good Clinical Practice (GCP).
