Vaccination
Vaccines are an integral part of modern preventive medicine. Without vaccines, not only would most malignant epidemics still be around, and the world would also be in a much more polluted era. The streets would be littered with diseased, there would have to be mass graves for the dead, and the healthy would have to be quarantined inside a sterile environment.
The history of differentiating between diseases and vaccinating them is a practice that has been used for more millennia than you can count on two fingers. In 900 BC, a Persian physician named Rhazes was the first to publish a written account attempting to distinguish between measles and smallpox (successful or not is a whole other matter). It takes about 2500 years before any more development in the field of vaccination. In 1661, Chinese Emperor Kiang wrote a letter that stated that he fully supports inoculation, which is the introduction of a pathogen or antigen into a living organism to stimulate the production of antibodies. Then in 1676, English doctor Thomas Sydenham publishes ‘Medical observations on the history and cure of acute diseases’ which successfully distinguishes measles from smallpox while in great detail. The report also stated details about Scarlet Fever which was big at the time. In 1678, a Boston newspaper published America’s first medical work, Thomas Thatcher’ pamphlet: A Brief Rule to Guide the Common People of New England how to order themselves and theirs in the Small Pocks, or Measles. Once again, Thomas Sydenham discovers a medical breakthrough in 1684 by concluding that the common health practices, not available to the poor, were more harmful than good in mild smallpox cases. Sydenham’s discovery would be the last big medical innovatio...

...of antitoxin and serum therapy in 1890. To get antitoxin, they immunized guinea pigs with heat-treated diphtheria toxin. They then discovered that they could cure diphtheria in animals by injecting the serum, blood products, from the guinea pig into the animal. Following the discovery of antitoxin, English physician S. Monkton Copeman discovered that adding glycerin to lymph makes it act as a germicide in 1891. The first big Polio epidemic will happen on June 17, 1894 in Rutland County, Vermont. Then, only 4 years after the discovery of the diphtheria antitoxin, Mulford Company of Philadelphia began to test and produce antitoxin in the US. Since there was no common standard for potency of an antitoxin container, each container had a different potency. To solve this, German scientist Paul Ehrlich developed a standardized unit of measure for the diphtheria antitoxin.
