In Kyoto, Japan, 68 of 606 children died after diphtheria immunization as a result of improper manufacture of toxoid.

Toxoid in the preparation reverted to toxin, with disastrous effects. Toxoid manufacturers instituted safeguards after this event to prevent similar incidents. No similar cases have since been reported.
