The big sore on the arm, if it was smallpox, would have formed a scab, and evenrtually a light flattish smooth and somewhat circular mark...

If you were vaccinated as a child, and aren't too old, you should have one on your arm or your thigh. Many times girls were innoculated on their thighs so they could wear sleeveless blouses and dresses without the scar showing on their upper arm.

Yeah, that's what I thought. I was vaccinated as a child, and they had the record of it, which was why I was not vaccinated in basic. The scar is very difficult to see now (I'm 35), but when I was younger it could be seen pretty easily. When done to adults, at least, it's really quite a nasty sore/scab for a while.
