RARE PIECE OF HISTORY COMMEMORATING VACCINATION RESEARCH by LOUIS PASTEUR: BACTERIOLOGIST: Medal Designed by Abram Belskie & Minted by the Medallic Art Company!

In the mid-nineteenth century, research brought many new insights about infectious diseases. The prominent French biologist, Louis Pasteur (1822–1895), introduced innovative experiments and techniques, which became fundamental to modern microbiology. He researched the microorganisms that cause dangerous diseases and discovered how to make vaccines from weakened microbes. Based on those studies, Pasteur developed the earliest vaccines against major veterinary diseases such as chicken cholera, anthrax, and rabies.
