do you know why there’s

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.

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.

Smallpox was once one of the most feared diseases in the world.

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.
