FIG. 5.

ELISA of antibody response after i.p. and i.n. vaccination. Mice were vaccinated either i.p. (A) or i.n. (B) with VSV-EnvG (solid bars), VSV-CT9EnvG (open bars), or VSV-CT1EnvG (hatched bars). Eighty-four days postvaccination, serum antibody titers to gp140 were analyzed using ELISA. Bars indicate the reciprocal dilution at which absorbance at 415 nm was 0.1 over the background. All bars indicate a pooled serum from at least three mice (± the standard error of the mean of triplicate wells). Background was obtained with control serum from unvaccinated mice.
