The National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health (NIH), has launched an early-stage clinical trial to evaluate an investigational preventative vaccine for Epstein-Barr virus (EBV).
EBV is the primary cause of infectious mononucleosis and is associated with certain cancers and autoimmune diseases. The Phase 1 study, which will be conducted at the NIH Clinical Center in Bethesda, Maryland, is one of only two studies to test an investigational EBV vaccine in more than a decade.
EBV is a member of the herpes virus family and one of the most common human viruses. It is spread through bodily fluids, primarily saliva. An estimated 125,000 cases of infectious mononucleosis occur each year in the United States; roughly 10% of those persons develop fatigue lasting six months or longer. Approximately 1% of all EBV-infected individuals develop serious complications, including hepatitis, neurologic problems, or severe blood abnormalities. EBV also is associated with several malignancies, including stomach and nasopharyngeal cancers and Hodgkin and Burkitt lymphomas, as well as autoimmune diseases, such as systemic lupus erythematosus and multiple sclerosis.
