What organization helped with smallpox?

The World Health Organization (WHO) played a crucial role in the global effort to eradicate smallpox. Launched in 1967, the Intensified Smallpox Eradication Program employed widespread vaccination campaigns and surveillance strategies to control the disease. This concerted effort culminated in the successful declaration of smallpox eradication in 1980, marking it as the first disease to be eliminated worldwide through human intervention.
