Brief Summary:
The purpose of this study is to compare the immune responses of two different doses (1.0 mg and 2.0 mg) and two different dosing schedules (two doses or three doses) of a mixed Hantaan virus (HTNV) and Puumala virus (PUUV) DNA vaccine in healthy participants. To maintain a blind, participants in the two-dose group will receive one dose of normal saline placebo. All of the groups will also receive a booster dose 6 months after first vaccination. The results will help to determine which dose and vaccination schedule will be best to move forward in the vaccine development process.
Detailed Description:
The study will enroll 4 randomized groups of 30 subjects each for a total of 120 subjects. These groups will be split so that 60 individuals receive the 1.0 mg dose and the other 60 receive the 2.0 mg dose. Every subject will receive a total of 3 injections on Days 0, 28, and 56. Half of each of these groups (n = 30) will receive 2 vaccine injections at Days 0 and 56 (normal saline placebo on Day 28) while the other half will receive 3 vaccine injections at Days 0, 28, and 56. All subjects will receive a booster dose at Day 168 to help assess immunogenicity with this booster dose. All doses will be administered with the TDS-IM device. All subjects will be followed until at least Day 252 (a 12 month follow-up visit may be requested). Subjects will complete post-injection memory aids for 7 days after each injection. There will also be up to 12 alternates enrolled and used to replace any original subject who fails to complete all 3 scheduled primary injections and Day 70 follow-up visit.
