If you feel it is warranted, you should. Worst case scenario if you need it and don't get it could be fatality... Worst case scenario if you get it and didn't need it is being UTD on your tetanus shot!
I am not a medical professional nor can I actually see your wound. I recommend just using your own judgment. If you need help deciding you could always call your doctor. I am sure they would answer your questions!
Here is a quote from the lovely world of the internet, maybe it will help you decide:
"The bacteria that causes tetanus comes from soil and it is everywhere. Most tetanus infections come from puncture wounds because the bacteria needs an environment that is not exposed to air. Its your choice whether or not to get a vaccine. If the wound is superficial, a shot isn't needed. If the wound is a puncture wound, any health professional would recommend a shot if you have not had one recently, or if you don't know when you last had a shot. Health authorities recommend getting a vaccine if you haven't had one in 5 to 7 years. Tetanus if an extremely painful condition, it is difficult to treat, and it is sometimes fatal. Seems like a shot is a small price to pay for avoiding potential complications." |
