The deaths attributed to ‘hydrophobia’, as rabies was called back then, actually increased after Pasteur’s rabies vaccine was implemented, including King Alexander of Greece, who was bitten by a monkey and succumbed after given Pasteur’s rabies vaccine. Quotes below from Ethel Hume’s Bechamp or Pasteur:

As the King instead, unhappily, grew rapidly worse, a discreet silence was, for the most part, observed as to his treatment, the truth as to which, however, we learn in a bulletin received by the Greek Legation in London and reported in the Daily Mail:—"Athens. Saturday. The King passed a critical night. His fever attained 105.6 deg. Fahr. and was preceded by severe shivering and accompanied by a fit of delirium, which lasted one hour and a half. This morning he was again vaccinated. His heart has weakened. His breathing is irregular.

Ah, but no mention of Pasteur’s rabies vaccine in Wikipedia’s article about King Alexander’s death!

It is, to say the least of it, remarkable that definite curative measures should be overlooked and set aside for a mere preventive which cannot set forward a single tangible proof of ever having saved anyone, while, on the other hand, as we have seen, there is undeniable evidence that it has occasioned a new complaint, paralytic hydrophobia. For such procedure there must be some explanation and perhaps the Indian paper, The Pioneer, for March 12, 1919, unconsciously provides it: —

"The Central Research Institute at Kasauli has developed its vaccine production to an almost incredible extent. The yearly average before the war was 18,500 cubic centimeters; during the war it rose to over 21 million cubic centimeters, and included anti-typhoid, cholera, pneumonia and influenza vaccines. From a monetary point of view alone the value of the Kasauli vaccines for the period of the war was about half a million sterling."
