The research, conducted in collaboration with other colleagues at the Paul Ehrlich Institute, led to the removal of previously mandatory animal tests from the European Pharmacopoeia.

To confirm that the inactivated material does not regain its toxicity during prolonged storage, the toxoid had to be tested in a guinea pig experiment after six weeks of storage at 37°C. For each batch 10 animals were consumed.

The prize is endowed with 20,000 euros.
