As I reminisce about my childhood, one particular memory stands out: the distinct scar on my mother’s arm. It intrigued me as a child, even though I couldn’t recall why. Over the years, I forgot about it, until I saw the same scar on an elderly woman. This reignited my curiosity and prompted me to delve into its origins.

I reached out to my mother, who reminded me that she had explained the scar’s cause multiple times before. It turns out that this unique mark was a result of the famous smallpox vaccine.

The Terrifying Smallpox Disease

Smallpox was an infectious viral disease that once plagued humanity. It caused a severe rash, accompanied by high fever, and was responsible for the deaths of 3 out of 10 victims during the worst outbreaks of the 20th century, according to the Centers for Disease Control and Prevention. Many survivors were also left disfigured.

The Triumph of Vaccination

Thanks to the widespread implementation of the smallpox vaccine, the virus was declared “extinct” in the United States in 1952. By 1972, smallpox vaccines were no longer part of routine vaccinations. However, prior to the ’70s, every child received the smallpox vaccine, leaving behind a distinctive mark—a scar that acted as a visible testament to successful vaccination.

How Did the Smallpox Vaccine Cause Scars?

The smallpox vaccine scar resulted from the body’s natural healing process. Unlike modern vaccines, the smallpox vaccine was administered using a special two-pronged needle. The person administering the vaccine made multiple punctures in the skin, reaching the dermis layer, which lies below the epidermis.

The vaccine introduced the virus into the body, causing round bumps to form. Over time, these bumps transformed into vesicles—small blisters filled with fluid. Eventually, the vesicles burst and formed scabs, resulting in the distinct scar we see today.

So, if you or someone you know bears this smallpox vaccine scar, it’s a mark of protection and a testament to their role in eradicating smallpox.
