I accidentally stabbed myself (causing a shallow wound with blood barely making it out) with a rusty old pin on something in my closet. The wound is not serious at all but of course with my HA I worry about tetanus b/c the old pin was rusty. I checked my vaccination record and my last booster was 9.5 years ago. I called my GP and she told me not to worry - the shot should last 15 years and anyway the cut did not occur outside in the street where there would be more bacteria around - so ignore it.

Should I worry???
