This is a timeline of diphtheria, describing major events such as epidemics and medical developments.

Big picture

Year/period Key developments
Ancient times Earliy detailed descriptions of dyphtheria date from ancient Syrian, Egyptian, and Greek writings.[1]
1600s onward Diphtheria infection grows significantly since the 17th century and becomes one of the major causes of death, fuelled by the Industrial Revolution and increasingly crowded urban centers.[2]
1800s Major scientific breakthroughs consolidate the knowledge on diphtheria, which is given its actual name in this century[2]. Bacterium corynebacterium diphtheriae and the diphtheria toxin are discovered.[3][4] Also, the first effective therapeutic serum against diphtheria is developed.[5]
1923 onward After the first diphtheria toxoid vaccine is developed, its subsequent widespread use would lead to a dramatic decrease of diphtheria rates worldwide.[6][7] A more than 90% decrease in number of cases globally results later, between 1980 and 2000.[8]
Recent years Currently most diphtheria cases occur in Sub-Sharan Africa, India, and Indonesia. Globally 4,530 cases were officially reported in 2015, down from nearly 100,000 in 1980.[9][8]

1905 Medical development Franklin Royer publishes a paper urging timely treatment for diphtheria and adequate doses of antitoxin.[8]
1907 Medical development Experiments start using a toxin–antitoxin (TAT) solution to induce protective immunity against diphtheria, under the assumption that the toxin would stimulate immunity and the antitoxin (antibodies) would counteract the toxicity of the toxin and prevent it from causing disease in the recipient.[1]
1907 Campaign Several cities in Europe and the United States begin immunization programs to administer the toxin–antitoxin (TAT) complex.[1] Europe, United States
1913 Medical development Emil von Behring publishes his diphtheria protective agent, T.A. (Toxin-Antitoxin), which contains a mixture of diphtheria toxin and therapeutic serum antitoxin. Designed to provide long-term protection, the new drug would further be tested at various clinics and proven to be non-harmful and effective.[5] Germany

1923 Scientific development French biologist Gaston Ramon, working at Pasteur Institute, develops diphtheria toxoid that could later be used for a toxoid vaccination. The product is licensed; prepared from inactivated bacterial toxin that has lost its toxicity but retaining its antitoxin producing properties. This would be considered the first diphtheria vaccine.[19][8][18] France
1924 Scientific development Gaston Ramon discovers diphtheria and tetanus toxoid, then referred to as anatoxins.[25] France
1926 Medical development British immunologist Alexander Glenny, working at Wellcome Research Laboratories, develops the adjuvant (the substance that enhances the body's immune response to an antigen) for the toxoid vaccine by increasing the effectiveness of diphtheria toxoid when treating it with aluminum salts.[8][19] United Kingdom (London)
