I'm assuming the dip/tet/polio vaccines I had as a child still have some efficacy *mumble* years later. Tetanus is the only thing there's a realistic, if small chance of getting, and to be fair, I probably still have enough immunity for it to only make me seriously ill, rather than dead.
Apparently if you ask your GP for a tetanus booster, you get given another shot of the combined childhood booster for all three though. Presumably because it's mass-produced and cheap.
