The global eradication of smallpox, officially completed in 1980, stands as one of the greatest triumphs of modern medicine. In 1967, when the World Health Organization (WHO) launched its Intensified Smallpox Eradication Programme, the disease was still endemic in more than thirty countries, infecting millions and killing hundreds of thousands annually. Through the international coordination of vaccine distribution, rapid containment of outbreaks, and public health campaigns, the chain of transmission was permanently broken. This achievement demonstrated how international cooperation and medical innovation could eradicate a disease that had plagued humanity for millennia.
