Louis Pasteur Uses First Successful Rabies Vaccine

On Monday 6 July 1885, Joseph Meister, aged nine, was brought to him from Alsace having been bitten by a rabid dog on 4 July. With some reluctance, Pasteur was persuaded by Drs Vulpian and Grancher of the Académie de Médecine to give Dr Grancher the emulsion from the cord of a rabbit that had died of rabies on 21 June, and had been kept in dry air for 15 days. The child was given 13 further inoculations in 10 days with portions of the cord that were progressively fresher (more
virulent), until after three months and three days he announced that the child’s life was now out of danger and his health appeared excellent. On 20 October, he successfully treated another patient infected by a mad dog six days earlier. By 1886, he had treated 350 patients from all over Europe, Russia, and America.
