In vivo imaging assessment of liposome-antigen-nucleic acid-complex vaccination strategy.

A) Average radiance in vaccinated, untreated, and uninfected mice at 48 hpi. Treated animals show significantly reduced luciferase activity (p<0.01) compared to untreated animals. Error bars indicate standard deviation. B) Corresponding images used for the quantitative analysis. Scale was normalized for all images and is shown on the left-hand side. Images presented are from 48 hours post intranasal challenge with WEEV.McM.FLUC.
