"History of vaccination against smallpox"

One of the great discoveries was made in the 18th century, when about 40 million people died from smallpox worldwide. Doctors could not find either the cause of the disease or a remedy for it. But in one English village, the talk that some of the locals are not susceptible to smallpox attracted the attention of a local doctor named Edward Jenner.

This picture shows how a person infected with smallpox dies.
There were rumors that dairy farm workers did not suffer from smallpox because they had already suffered cowpox, a related but milder disease that affected cattle. Cowpox patients had fever and ulcers on their hands.
Jenner studied this phenomenon and wondered if the pus from these ulcers somehow protects the body from smallpox? On May 14, 1796, during an outbreak of smallpox, he decided to test his theory. Jenner took the liquid from the ulcer on the hand of a milkmaid with cowpox. Then, he visited another family; there he injected a healthy eight-year-old boy with the cowpox virus. In the following days, the boy had a slight fever, and several smallpox blisters appeared. Then he recovered. Six weeks later, Jenner returned. This time he vaccinated the boy with smallpox and waited to see if the experiment would turn out to be a victory or a failure. A few days later, Jenner received an answer – the boy was perfectly healthy and immune to smallpox.

The invention of smallpox vaccination revolutionized medicine. This was the first attempt to intervene in the course of the disease, preventing it in advance. For the first time, human-made products were actively used to prevent the disease even before it appeared.

50 years after Jenner's discovery, Louis Pasteur developed the idea of vaccination by developing a vaccine against rabies in humans and anthrax in sheep. And in the 20th century, Jonas Salk and Albert Sabin independently created a polio vaccine.
