The tetanus vaccine is only good for ten years anyway. How many people have kept up with their boosters since high school? Not too many from my experience (I used to work in a doctors office and the only time an adult ever came in for a tetanus shot was because they had cut themselves). So that basically means that the majority of us are running around with no immunity to it anyway, even though we had the shots as children.
