Public Service Announcement: this is what a "normal" smallpox vaccination looks like. I had no idea. No wonder it leaves a mark.
It seems downright medieval, doesn't it? Funny how we've developed medicine to the point where we can measure the resonant magnetism of the body and determine useful things from that, but making sure we don't get a terrible disease is still so... backwards.
I know it probably represents the state-of-the-art of 40 years ago, and I understand how it works, but still!
