A booster for smallpox? My understanding is that once you have cowpox (a mild disease that is the vaccine for smallpox) you are immune from smallpox.

I thought the same thing.I know that I was vaccinated for smallpox in the Navy too as well as a number of other things. Over a 26 year career I was needled and air gunned so many times it was hard to keep up with all the details. I do know the I had shots for bubonic plague once and I wonder if that one is permanent or needs a booster too.
