Detailed Description:
Dengue is a desease that affects 100 million people throughout the world mainly in tropical countries in the South Pacific, Asia, the Caribbean, and Africa. The disease often presents with high fever, severe headache, and joint/muscle pain that usually goes away on its own, but it can also present as a sometimes deadly hemorrhagic (bleeding) disease. Humans catch this disease by being bitten by mosquitoes that have been infected with dengue virus. Scientists at the Naval Medical Research Center have been working on vaccines to prevent dengue disease. This vaccine, referred to as D1ME, is an experimental DNA vaccine that contains genes from the dengue-1 virus. The purpose of this study is to test the safety of a new experimental vaccine against dengue and to see if the vaccine can stimulate the immune system.

  • Plan to have elective surgery during the study period
  • HIV infection
  • Known immunodeficiency or currently receiving immunosuppressive therapy (inhaled and topical steroids are allowed)
  • History of splenectomy
  • Administration of a vaccine not foreseen by the study protocol during the period starting 30 days before each dose of vaccine and ending 30 days after vaccination
  • Evidence of active (acute or chronic) hepatitis B or C infection
  • Autoimmune diseaseor subjects who describe a first-degree relative with clearly documented autoimmune disease
  • Acute or chronic, clinically significant cardiac, pulmonary, hepatic, or renal abnormality, as determined by physical examination or basic laboratory screening
