When was the first vaccine against tetanus introduced?
Quick Answer
The tetanus toxoid vaccine was introduced in the 1920s and became widely used by the 1940s. It greatly reduced tetanus deaths after injuries and childbirth.
The Full Story
The tetanus toxoid vaccine was developed in the 1920s and was widely adopted in the following decades. Tetanus is caused by a toxin from Clostridium tetani, so the vaccine uses an inactivated toxoid to train the immune system. It became especially important for wound care and for preventing neonatal tetanus. Routine immunization made tetanus much rarer in many parts of the world.
