The purpose of this Phase 1 trial is to evaluate the clinical safety of HBV-002 vaccine in healthy adults.
West Nile virus is an emerging infectious disease in the U.S. and worldwide and has been identified by the CDC as a significant public health risk. Since the introduction of West Nile virus into the U.S. in 1999, annual outbreaks have caused severe and fatal encephalitis in humans and equines and death in a variety of species of feral birds throughout the U.S. and parts of Canada. In addition, more recent findings show evidence of West Nile virus human and equine infection in several countries of tropical America. The virus has now been found in bird populations in all 48 states of the continental U.S, and human cases of West Nile disease have been documented in 45 states and the District of Columbia. To date, there is no approved commercial vaccine available for prevention of West Nile virus disease in humans.
