Who invented the first vaccine, marking a turning point in the fight against infectious diseases?

Edward Jenner

Edward Jenner, often regarded as the father of immunology, revolutionized medicine by developing the world's first vaccine against smallpox in 1796. Using material from cases of cowpox, he demonstrated that inoculation could provide protection against this deadly disease. His work not only saved countless lives but also laid the groundwork for the development of modern vaccines. Today, thanks to vaccination, smallpox is the first disease to have been eradicated by human efforts.
