| Outline of Final Research Achievements |
Quality control of vaccines largely rely on animal experiments. Potency tests for tetanus toxoids employ animal challenge with tetanus toxin sometimes stressful to animals. To avoid unnecessary stress by in vivo challenge method, we tried to construct a system for tetanus toxoid potency test, with less stress to animals. The test system needs to measure toxin-neutralizing activity in immunized animals accurately and sensitively enough to be applied in quality control of vaccines. Our results suggest, although not immediately applicable to routine testing, a possibility of developing an in vitro test system by further studies.
