Figure 3From: Multiple vaccinations with UV- attenuated cercariae in pig enhance protective immunity against Schistosoma japonicum infection as compared to single vaccinationSchistosome antigen-specific IgM and IgG responses in different swine groups. Vac3-Cha and Vac3-Con groups were immunized with UVAC at weeks 0, 4 and 8. The Vac1-Cha group was immunized only at week 8 (triangles). The Vac3-Cha, Vac1-Cha and Cha-Con groups were challenged with normal cercariae at week 12 (arrow). *P < 0.05 for the triple vaccinated compared with the Cha-Con group. Values depicted are means ±SEM for results from six animals.Back to article page
