I gouged my left thumb with the fingernail on my right thumb. I had been cleaning and this nail was very dirty. I immediately cleaned it & within 40 minutes was able to clean it again with peroxide & bacitracin. My question is I had a tetanus shot 3 years ago-am I alright or do I need another shot, etc.?
Theoretically you need not have to get immunized with tetanus toxic shot if you have completed the tetanus immunization schedule & received the shot in previous five years. But considering the cost-effectiveness & the dangers caused by the disease tetanus(if at all it developed) it is a regular practice to advice the tetanus toxic shot if the wound is encountered by the object harboring the dust which is the habitat for tetanus spores and the person has not received the toxic within last 6 to 12 months.  Anyhow taking a toxic is not going to produce any harm so better to go for it.
