An Incredible Defense against Smallpox

To protect people from the highly contagious Variola virus that caused smallpox, a vaccine called live Vaccinia virus was used. This vaccine stimulated a strong immune response, creating a powerful shield against the threat of smallpox.

The Signature of Healing

After receiving the vaccine, blisters would appear at the injection site. Over the course of a few weeks, these blisters would heal and form a crust. But why are these scars so noticeable?

The answer lies in the process. When the needle punctured the skin, a small amount of the vaccine was intentionally applied, which caused the blisters. The scars we see today are a testament to the deliberate application of the vaccine, serving as a reminder of the protection it offered against smallpox.

The Incredible Journey of a Scar

Let’s explore the fascinating journey of a smallpox vaccination scar.

Immediately after the shot, the area where the vaccine was given would slightly expand for the next 6 to 8 hours. Then, the swelling would go down, and the injection site would look normal.

After about 6 to 8 weeks, a small lump, similar to a mosquito bite, would appear again. Although it may seem worrisome, don’t be alarmed! This lump would undergo its own transformation, gradually growing and developing into a tumor before eventually breaking open. Fluid would start to seep out, leading to the formation of an ulcer.

As the sore went through the healing process, a scar would slowly form. This entire journey, from the appearance of the lump to the complete healing of the ulcer, would take about two to five weeks. Interestingly, this process of ulceration and healing could happen two or three times, leaving behind a scar that would never fade away.

The Disappearing Threat

Luckily, smallpox was mostly eradicated in the Western world by the early 1970s. As a result, vaccination became unnecessary for most people unless they were traveling to regions with active smallpox cases.

In fact, in the 1980s, smallpox vaccinations were completely stopped, as it was determined that the general population was no longer at risk of exposure to the Variola virus.

Embrace Your Hidden Symbol

So, if you have a small scar on your upper arm, cherish it as a hidden symbol of immunity. It reminds us of a time when the smallpox vaccine played a vital role in protecting communities around the world.
