I ve been bitten by my friend when she was seizing during an epileptic fit do i need to get a tetanus shot ?

GET seen,GET Tetanus: Human bites can be as dangerous as or even more dangerous than animal bites because of the types of bacteria in the human mouth. First aid is: wash the wound thoroughly with soap and water. Apply a clean bandage. Cover the affected area with a nonstick bandage. Seek emergency medical care. If last tetanus > 5 years get one (get whooping cough with it). Prevent infection.

Yes.: For human and animal bites you should be getting a tetanus shot if you're not up to date (having one within the past 5-10 years). If you can't remember when you last got one, it's safe and recommended to get ahead one anyways (even if you find out later you had it just last year). Hope this helps!
