The Full Story
The diphtheria toxoid vaccine was introduced in the early 1920s, with broad use beginning after 1923. It transformed a once-feared childhood disease into a much rarer illness in countries with high vaccination coverage. The vaccine works by using an inactivated toxin rather than the bacterium itself.
