“The vaccination against malaria was certainly a risk, the outcome of which could not be foreseen. It was dangerous for the patient himself and this to a much higher degree than the treatment with tuberculin and other vaccines, and it also was a danger for the surroundings and even for the community.” And, on page 136, it states “Three patients died after having been vaccinated with blood infected with malaria tropica and not with malaria tertiana”; and “The tragic outcome of this experiment was discouraging, and only a year later could the author decide to proceed with the malaria vaccinations * * *.” Nobody talks of these victims today, but Wagner-Jauregg’s revolutionary discovery is known and adopted throughout the world and has become the common property of all peoples for the benefit of suffering mankind. These doctors who knew that the fight against disease and death was a thorny path were all more than ready to sacrifice their own lives. The real scientist and the real doctor, therefore, do not oppose each other. However, the scientist must not forget that nature is the expression of the divine will and that only this cognition can save him from the “hybris”, the boundlessness which for the Greek tragedians was the greatest vice of mankind. Above all, the words of the greatest German physician, Theophrastus Bombastus von Hohenheim, called Paracelsus, must be applied to both scientist and doctor “The doctor grows with his heart, he comes from God and is enlightened by Nature—the best of all drugs is Love.” My learned colleagues have compiled a long list of documents on human experiments especially from the Western democracies. It would be unjust, however, to conceal the enormous benefit of the human experiment. The fact that Paul Ehrlich dared to release his drug “Salvarsan” before it had been sufficiently tested saved thousands from the dangerous consequences of one of the worst epidemics. The fact that Strong took the responsibility upon himself to perform the probably very dangerous experiment with plague bacilli made it possible to vaccinate thousands of persons and to save them from almost certain death. The fact that Strong was in a position to prove that beri-beri was a disease caused by a deficiency, and that Goldberger proved the same for pellagra, made it possible to fight this deficiency and to liberate entire countries from one of their worst diseases. With regard to the criminal law, however, and the judgment of crimes against humanity, it is the decisive result that in other countries, too, under their own generally prevailing medical and ethical convictions, doctors carried out similar or the same experiments for the benefit of scientific research or in consideration of a crisis in their country.
