To stop its spread, scientists, doctors, and health workers carried out massive vaccination campaigns around the world. They traveled even to remote communities to make sure people could receive protection.
The vaccination often caused a small blister that later healed into a permanent round scar. For many people, that mark became a lasting sign that their body had been protected against one of history’s most dangerous diseases.
After years of global effort, smallpox was officially declared eradicated in 1980. Today, that small scar remains a reminder of what science, vaccination, and worldwide cooperation were able to achieve.
