the good news is: probably not. the dtap vaccine (which includes dipetheria tetanus and pertussis) is considered protective for 10 years. we recommend everyone get re-vaccinated with dtap every decade. that said the only way to tell for sure you're protected (because not all vaccines "take" the way they're supposed to) is to look at your blood antibodies. if your blood contains antibodies toward tetanus then you're golden. bottom line: your best bet is to consult a health care provider. even if you're up to date on your tetanus vaccination that wound could get infected with bacteria which could cause problems. better to have it looked at and washed out if necessary. hope this helps!
