Neutralizing antibodies in rabbits after vaccination with SNV DNA vaccine delivered by PharmaJet IM or ID device. A ) Experimental design. Groups of four rabbits were vaccinated with 0.4 mg of pWRG/SN-M(opt) plasmid DNA using the indicated PharmaJet device. For IM, a single injection of 0.5 mL of vaccine was delivered per vaccination. For ID, a single injection of 0.1 mL was delivered per vaccination. Sera from the IM-vaccinated rabbits were collected on weeks 0, 4, 6, 8, and 10 (light grey arrows) and sera for the ID-vaccinated rabbits were collected on weeks 0, 3, 7, and 12 (dark grey arrows).

Hantavirus DNA vaccine delivered to NHP using PharmaJet IM v1.0 or ID v1.0 needle-free jet injection device. A. Groups of three NHP were vaccinated with the SNV DNA vaccine (pWRG/SN-M[opt]) using either the PharmaJet IM v1.0 or ID v1.0 device three times at 4-week intervals (arrows). Each vaccination consisted of two administrations of 0.5 mg of DNA/administration, one to each triceps muscle. B . SNV PsVNA 80 titers were determined and plotted. The animal ID numbers and device (IM or ID) are shown in legend. C. SNV PRNT 50 titers were determined and plotted to quantify the capacity of the sera to neutralize authentic virus.

Delivering the HPS DNA vaccine as a mixture, or to separate sites. A ) Experimental design. Rabbits were vaccinated on week 0, 4, and 8 with: Group 1: HPS vaccine (1:1 mixture of SNV DNA vaccine, pWRG/SN-M(opt); and ANDV DNA vaccine, pWRG/AND-M(opt2)) delivered to two sites; Group 2: the ANDV DNA vaccine alone (1 site); Group 3: the SNV DNA vaccine alone (1 site); or Group 4: the ANDV and SNV DNA vaccine to two separate sites. Sera were collected on indicated weeks (grey arrows). In all groups, 2 mg of DNA was injected in a 0.5 mL volume per administration. Groups 1 and 4 received 2 administrations per vaccination, one to the right and left lateral thigh muscle. Groups 2 and 3 received a single administration per vaccination. B ) PsVNA 80 titers for SNV and ANDV are shown for weeks 4, 8, and 12. Geometric mean titers +/- 95% confidence intervals are shown. Significant differences between delivery devices are shown p <0.05 *, as determined by Wilcoxon Test. Titers above 1,000 (large-dashed line) are considered high-titer.
