Victor Babeș introduced rabies vaccination in Romania, only three years after its initiation by Louis Pasteur. He is considered the second rabiologist in the world after Pasteur and the father of serotherapy, precursor to modern immunology. His work also had a strong influence upon veterinary medicine, especially concerning prophylaxis and serum medication. He prepared the anti-diphtheria serum and conducted broad activity in researching pellagra, tuberculosis, typhoid fever and leprosy. He has published over 1,000 scientific papers and 25 monographs in the field of microbiology and pathology.
