Clinical Trials Center


The Clinical Trials Center (CTC) was established in early 1992 to support Army and Navy investigators in their mission to develop new vaccines, drugs, and diagnostic systems to meet high-priority Department of Defense and national security needs. As part of WRAIR, the CTC is fully integrated within a network designed to bring products to market with an average of 5-10 new studies each year.

Since its inception, the CTC has conducted over 150 clinical trials of drugs and vaccines for a variety of infectious diseases, including Ebola, Japanese encephalitis, Zika, HIV and many others.

WRAIR #2725- Phase 2 Hanta PharmaJet Vaccine Trial


This is a phase 2 study that is intended to assess two experimental vaccines at low and high doses; the Hantaan Virus DNA Vaccine and Puumala Virus DNA Vaccine. Phase 2a means that these vaccines have been tested in humans previously, and the results showed that they were safe and well tolerated. We repeat the study with more people and different doses, to verify the safety and get more data on the best dose for protection.

The main purpose of this study is to confirm that these vaccines are safe and tolerable. Another purpose of this study is to see if this experimental vaccine helps your body to make the antibodies that protect against hantaviruses.

To learn more about the Phase 2 vaccine trial or to enroll, contact the WRAIR Clinical Trials Center at 866-428-2788 or through email.

WRAIR #2924- Phase 1 RV 575 Vaccine Trial


Researchers are doing this study to test an experimental vaccine for HIV. A vaccine is a medical product given to prevent certain infectious diseases, most often caused by a virus or bacteria (germs). A vaccine may teach the human body to form a defensive response to try to prevent the disease from beginning or taking hold of the body. This defensive response is called an immune response, and is the body’s way to fight infections.
The study also tests a combination of adjuvants. An adjuvant is a substance added to vaccines that can help to make the vaccine more effective by improving the immune response or causing the immune response to last longer than without the adjuvant.
