In brief: 5 years if wound
Tetanus vaccine is valid for 9 years if you have no injuries.
If you have an outdoor laceration or puncture wound, you should get vaccinated within 24 hrs if your prev tetanus is older than 5 years. If you have not had a tetanus vaccine since 2005, you should get booster that contains pertussis vaccine also. This will protect you and children around you from whooping cough.

In brief: Tetanus vaccine
After receiving the primary immunizations, a booster tetanus shot should last 10 years.
This is the basis for having a tetanus booster every 10 years during one's lifetime.
