Mouse Response

  • Vaccine Immune Response Type: VO_0000286
  • Efficacy: CT-SOD showed the highest level of protection out of all vaccines tested (54%). Two immunizations resulted in significant reduction of worm burden compared to control groups (Shalaby et al., 2003).

Mouse Response

  • Vaccine Immune Response Type: VO_0000286
  • Efficacy: For the regimens involving GPXbb, immunization with DNA vaccination alone resulted in protection of 44%, but the prime-boost (boost of recombinant vaccinia virus/GPXbb) resulted in 85% worm burden reduction (Shalaby et al., 2003).

Mouse Response

  • Vaccine Immune Response Type: VO_0000286
  • Efficacy: Mice immunized with Sm-p80-pcDNA3 showed statistically significant 39% reduction in worm burden when compared with mice which received only pcDNA3. Similarly, mice immunized with Sm-p80-pcDNA3 and co-injected with pORF-mIL-2 exhibited 57% reduction (P≤0.0001) in the number of parasites when compared with the group of mice receiving only pcDNA3 and pORF-mIL-2. Also, when mice were primed with Sm-p80-pcDNA3 in the presence of pORF-mIL-12, they contained 45% less number of parasites (P≤0.0001) compared to the group of mice which were immunized with pcDNA3 alone (Siddiqui et al., 2003).

Mouse Response

  • Vaccine Immune Response Type: VO_0000286
  • Efficacy: The Sm23-pcDNA vaccine provided statistically significant levels of protection against challenge infection (21-44%, P<0.001-0.02) (Da'dara et al., 2001).
