Schistosomiasis Vaccine Study

Schistosomiasis Vaccine Study

We are currently recruiting participants for a clinical trial of an investigational vaccine against schistosomiasis. The trial is sponsored by the U.S. National Institutes of Health (NIH).

Schistosomiasis is a disease caused by a worm-like parasite. Globally more than 200 million people are infected worldwide, most commonly in sub-Saharan Africa, leading to hundreds of thousands of deaths each year. There is currently no approved vaccine for schistosomiasis. This investigational vaccine, called Sm-p80 + GLA-SE (SchistoShield®), includes a synthetic protein made in a laboratory and the GLA-SE adjuvant, which is a substance that increases the body’s response to vaccines. It does not contain any parts of the schistosomiasis parasite and cannot cause infection. The goal of this study is to evaluate the safety of and immune responses to the Sm-p08 + GLA-SE vaccine.

The study involves three injections of the investigational vaccine, with up to 13 scheduled study clinic visits and 2 telephone visits over a period of up to 19 months. The vaccination visits will take up to three hours, and the other clinic visits will take about 30 minutes. Participants will receive a $75 payment for each clinic visit. Free parking or bus tickets are provided.

Participant Eligibility

• Healthy adults age 18 to 55 years
• Able to attend all study visits at the Kaiser Permanente Washington Health Research Institute clinic in downtown Seattle
• Not pregnant, and if able to become pregnant, willing to use an acceptable form of birth control
• No medical conditions that affect the immune system and not taking medications that affect the immune system
• No previous potential exposure to schistosomiasis (swimming or wading in freshwater sources, like lakes or rivers, in Africa or other parts of the world where schistosomiasis occurs)
• There are other conditions that may make you ineligible for this study
