Have you ever noticed a small round scar on the upper part of your arm, like the one in the photo?
For many older Americans, that little mark is more than just a scar. It’s a reminder of a time when one of the world’s deadliest diseases was finally brought under control.
What Is This Scar?
The small, round scar is usually left behind by the smallpox vaccine.
If you were born before the early 1970s, there’s a good chance you received this vaccine as a child. Millions of Americans have the same mark.
Unlike most modern vaccines, the smallpox vaccine often left a visible scar that stayed for life.
Why Was the Vaccine So Important?
Smallpox was once one of the most feared diseases in the world.
It was caused by the Variola virus and could lead to:
High fever
Severe rash
Painful blisters
Permanent scarring
Blindness
Death in many cases
For centuries, smallpox killed millions of people around the globe.
Before vaccination became widespread, outbreaks could spread quickly through entire communities.
