John, this is quite worrying, effective Smallpox vaccination doesn't just require the shot/scratch to be given correctly it also needs a checkup a few days later.
I wonder if the Smallpox vaccine they used on you had been diluted? The government was debating this a few months ago.
I can call my civilian MD tomorrow. I saw her today, and updated my civilian records with my shot record info. She didn't ask anything about a scar, but was glad that I got the vaccination, and equally glad that I didn't get the anthrax.
