I am pro-vaccination but with this one I know you can avoid the risks with tetanus with good wound care. My DH had an allergic reaction to the booster as a baby so went all his life without a shot. Now he has regularly worked with rusty stuff, nails, welding, metalwork, fallen off bikes, cut himself, the works. He was just SUPER CAREFUL with wound care. Tetanus needs an anerobic (ie: no-oxygen environment) to live in, so if you clean the wound BEFORE it heals you should be ok. As it turns out he had the tetanus shot last year without reaction (aged 36) because his doc said he was nuts not to. So I am not saying yay or nay, but rather you can lead a "high risk" lifestyle and not get tetanus.
