Humoral responses in mice. Mice were intramuscularly inoculated with two doses of rLa-WNV-PrM/E with a 3-week interval. Serum ELISA antibody to WNV E (a), neutralizing antibody against WNV (b) and neutralizing antibody to NDV (c) were assessed at different times post-inoculation. Data are presented as mean ± SD for each group. (a), (b), and (c): p < 0.01, significance of the differences in antibody amounts between the first and second dose
