Should I get another tetanus shot?

I had a tetanus shot about 3 years ago, but today I was pricked by a metal ruler, and can tell it penetrated my skin. It’s not rusted, but is old.

    The tetanus bacteria live in soil and cannot exist for very long out of it. So only if thre metal ruler had been in soil would it have a possibility of carrying tetanus.

    The TDAP shot should last approximately ten years.

    You should really only need a shot every decade or so.  Unless the ruler cut in deep enough to cause excessive blood loss or a need for stitches, you should be ok.  But call up your gp and verify with them just in case.
