A Distinctive Circular Scar

Did you know that the little, rounded scar on your upper arm holds a significant story? For those of us between the ages of 45 and 65, this scar is a lasting reminder of the smallpox vaccination we received before the 1970s. The vaccine and the scar it left behind played a crucial role in safeguarding our communities from the dangerous Variola virus that caused smallpox. Let’s delve into the captivating journey of this vaccination and the remarkable scar it bestowed upon us.

When you received the smallpox shot, a live Vaccinia virus was used to stimulate your immune system and protect you from Variola. After the injection, blisters would develop at the site. Within a few weeks, these blisters would heal and form a crust, leaving behind a distinctive circular scar. The reason it is so visible is due to the tiny amounts of vaccine applied each time the needle pierced your skin, causing the blisters to form and the scar to appear.

Immediately after the shot, you might have noticed the area where the injection was given slightly expanding. This mild swelling typically lasted for about 6 to 8 hours before disappearing, leaving the injection site looking normal. However, after around 6 to 8 weeks, a small lump resembling a mosquito bite would reappear. This lump would gradually grow and transform into a tumor-like formation that eventually cracked open, releasing fluid and developing into an ulcer.

The Healing Process

As the sore went through the healing process, a scar would form. It would take two to five weeks for the entire process of ulceration and healing to be completed. In some cases, this cycle of ulceration and healing would occur two or three times. The end result was a scar that would remain with you for a lifetime, serving as a tangible link to the vaccination’s journey and its protective power.

A Remarkable Achievement

Fortunately, after the early 1970s, smallpox was eradicated in the vast majority of the Western world. This meant that people no longer needed to receive the smallpox vaccination unless they were traveling to areas where the virus still existed. The successful eradication of smallpox stands as a significant achievement in humanity’s health. In the 1980s, it was determined that people were no longer being exposed to the Variola virus, leading to the complete discontinuation of smallpox vaccinations. This marks a remarkable milestone in the history of medical science.

A Symbol of Our Protective History

While the smallpox scar on your upper left arm is a reminder of a bygone era, it serves as a tangible link to a time when vaccination played a crucial role in safeguarding our communities against deadly diseases. It reminds us of the incredible story it carries and how it contributed to protecting our world.
