Abstract

Mankind fought smallpox for centuries, culminating in its eradication in the late 1970s. This remarkable achievement was due to a global vaccination campaign led by the World Health Organization (WHO). The smallpox vaccine was developed in the late 18th century by Edward Jenner, and it was one of the first vaccines to be used to prevent a disease. The WHO-led campaign began in 1967, and it involved vaccinating millions of people in dozens of countries. The campaign was successful in eradicating smallpox from the world, and it is considered to be one of the greatest public health achievements of the 20th century. – AI-generated abstract.
