Survivors often bore lifelong reminders of their struggle, with scars frequently etched into their faces.

The vaccine spurred the immune system to produce antibodies capable of fighting off smallpox.

Thanks to this medical breakthrough, smallpox was declared eradicated in the early 1950s, a feat so monumental that routine vaccinations in the United States ceased in 1972.

Today, only those working in high-risk environments, such as labs handling the virus, receive the vaccine
