I clearly remember seeing a unique⁢ scar on ‍my⁢ mom’s arm when I was younger. It’s located high ​up, near her shoulder, looking like a circle of⁤ tiny ​indentations around a bigger one.
I can’t say ‌why that caught my eye back then; I just know it did. Over the years, though, I kind of forgot about it.

Of course, I didn’t ⁣completely forget (it’s still there), but I did lose track of why it fascinated me. Maybe I asked my mom once and she told me. If she did, though, that slipped my​ mind too.

That changed when I helped an older lady off a train one summer not ⁢long ago and noticed the same⁤ scar in the same spot as ⁤my mom’s. My curiosity was sparked but with the train moving on to where I needed to‌ go, asking her about her scar wasn’t possible.

So instead, ‌I called my mother who told me she had explained more than⁤ once – obviously not important⁣ enough for me to ⁢remember – that her scar came from the well-known smallpox vaccine.

Smallpox is an infectious virus that used to frighten people everywhere. It caused serious skin rashes and fevers; during ⁢major outbreaks in the 20th ​century, it killed about 3 out‍ of every 10 people infected‍ according to the Centers for Disease Control and Prevention. Many others were left with permanent scars.

Thanks to effective use of the smallpox vaccine across⁣ many⁤ communities, this virus was declared “extinct” in America ⁤by​ 1952! In fact by 1972 smallpox vaccines stopped being part of regular shots given to kids.

However until the early ’70s all children received this vaccination which left behind noticeable marks. Think of​ it as an ​early version of a vaccine‌ passport: a scar showing you had been vaccinated against smallpox!

And yes ⁤you guessed right; it’s that very mark on my mother (just like⁤ almost‌ everyone else from her generation).

Why does the smallpox vaccine leave scars?

The⁤ scarring from this vaccine happened​ because⁤ of how our bodies heal themselves. The way this vaccine was given is quite​ different compared to most ⁣vaccines today—it used a special two-pronged needle.

The person ⁣giving out this shot made several⁣ punctures into​ your skin (instead of just‍ one like today) so they ‌could deliver it into your dermis (the layer under your outer‌ skin).

Then inside your body ,the virus would start multiplying causing round bumps to form which later turned⁣ into vesicles (small blisters filled with fluid) before bursting and scabbing over‍ eventually.

This‍ process leads us back to⁣ that famous scar we’ve​ discussed ⁤here!
