Figure 4. Rapid protection against WNV infection conferred by nonintegrative lentiviral vector immunization.
Six mice/group were vaccinated with 100 ng of TRIP.NI EWNV or 100 ng of TRIP.I EWNV. A control group of mice inoculated with phosphate-buffered saline (PBS) was included. One week after the vaccination, mice were challenged with 1,000 i.p. LD50s of WNV strain IS-98-ST1. Survival was recorded for 21 days. Data are representative of three independent experiments.
