The word I've had is that without booster shots there's no telling how much the shots from childhood would help. I've heard one estimate of 10 years, which won't help any of us too much. We can only hope for milder cases, I guess. I find it amusing that my husband's scar is on the top of his arm and mine is on the underside. Apparently they didn't want a little girl to have a visible scar in those days.
Mine is on top of my arm and very visible - I had a photo taken recently in which it really stands out. From what I've read, it really matters where the vaccine is administered - and it has to be done in a certain way, it's not just like giving any shot. I'll have to look for the proper thread to address these concerns.

They stopped Smallpox Vac's in 1972.
