Mass vaccination to prevent diphtheria had already started in the Western countries since the Twenties, so it had ceased to be a very common disease in the US and Europe. In countries that had no vaccination program it remained a common children's disease. Only in Europe after the outbreak of WW II, there was an outbreak in 1943 with a million cases and about 50,000 deaths.
