How do vaccines contribute to the eradication of a disease like smallpox?
MedicineHistory
Quick Answer
They stop transmission by building enough immunity that the virus cannot keep finding new hosts. With surveillance and targeted vaccination, the disease can disappear from the wild.
The Full Story
Smallpox is the classic example of vaccination leading to eradication. A global campaign led by the World Health Organization intensified after the 1960s and used ring vaccination around cases, combined with surveillance and containment. The last naturally occurring case was in Somalia in 1977, and eradication was certified in 1980. This remains the only human disease eradicated by vaccination and public-health action.
