Which scientist developed the first widely used antivenom serum for snakebite?

Albert Calmette developed the first widely used antivenom serum for snakebite. Working in French Indochina in the 1890s, he studied cobra venom and created an antiserum by repeatedly exposing animals to small, controlled doses.

Calmette’s work showed that blood serum from immunised animals could neutralise venom. In 1895, he published research on an antivenom against cobra bite, helping establish serum therapy as a practical medical approach.

Antivenom is not a universal medicine: it is produced against particular venoms or groups of related venoms. Modern treatment therefore depends on identifying the snake when possible and selecting the appropriate product. Supportive hospital care remains essential because venom can damage nerves, muscles, blood clotting and tissues.

Calmette is also remembered for co-developing the Bacillus Calmette–Guérin vaccine against tuberculosis. His snakebite research was an earlier milestone in immunology and emergency medicine.
