This is a Phase 1, randomized, placebo controlled, double-blind, dose escalation trial of 48 males and non-pregnant females, 18-49 years old, inclusive, who are in good health and meet all eligibility criteria. This trial is designed to assess the safety, reactogenicity and immunogenicity of an Andes Virus (ANDV) DNA vaccine for the prevention of Hantavirus Pulmonary Syndrome (HPS). ANDV DNA vaccine or placebo will be administered using the PharmaJet Stratis(R) Needle-Free Injection System. The study duration is 23 months while the subject participation duration is 12 months. Subjects assigned to the 3 dose regimen will receive ANDV DNA vaccine on Days 1, 29 and 169, and placebo on Day 57. Subjects assigned to the 4 dose regimen will receive ANDV DNA on Days 1, 29, 57 and 169. Two doses (2 or 4 mg) of ANDV DNA vaccine will be evaluated. The primary objective of this study is to assess the safety and reactogenicity of the ANDV DNA vaccine by dosage cohort and treatment arm when administered using the PharmaJet Stratis(R) Needle-Free Injection system in normal, healthy adults. The secondary objective of this study is to assess the immunogenicity of the ANDV DNA vaccine by dosage cohort and treatment arm.
