Which scientist conducted the development of the first attenuated vaccine in 1880 and vaccines for anthrax and rabies?

Attenuation-based vaccination relies on weakening a pathogen so it can’t cause disease but still prompts a protective immune response. Louis Pasteur popularized this approach, demonstrating that immunity could be achieved with a live but weakened organism. He developed an attenuated vaccine against anthrax, showing animals could be protected by vaccination with a dampened Bacillus anthracis, and he extended the same idea to rabies, producing the first vaccine that protected against that disease. These milestones established the practical use of weakened pathogens to prevent disease and cemented Pasteur’s role in immunology. The other scientists are known for different breakthroughs: Emil von Behring pioneered serum therapy for diphtheria and tetanus, Rudolf Virchow made foundational contributions to cellular pathology and public health, and Wilhelm Roentgen discovered X-rays.
