What is the only human disease to have been completely eradicated by vaccination? Explained

Smallpox stands as the sole human disease that has been completely eliminated through vaccination. Stemming from the variola virus, smallpox inflicted devastating epidemics on mankind for millennia. Edward Jenner’s groundbreaking efforts in 1796 towards developing the smallpox vaccine paved the way for contemporary immunology. In 1967, the World Health Organization initiated a worldwide eradication initiative, and following extensive vaccination efforts, the final naturally contracted case was documented in Somalia in 1977. The official announcement of smallpox’s eradication was proclaimed by the WHO in 1980.
