Figure 3From: Evaluation of the immune responses induced by four targeted DNA vaccines encoding the juvenile liver fluke antigen, cathepsin B in a mouse modelCat B2 specific IgG antibody responses in vaccinated mice at bi-weekly intervals from weeks 4 to 10 after the first vaccination. At every time point, all vaccinated groups with Cat B2 encoding constructs showed enhanced antibody titres when compared with control vectors P < 0.05).Back to article page
