[|Human|] Hi my name is omar and i am 15 years old. I barley stepped on a nail and it barley pierced my skin. I got a tetnus shot four years ago. I cant even find in what part of my foot the nail went in, thats how small the injury was. I dont even feel any pain. Should i still get a tetnus shot?
[|AI|]  Dear Friend. Welcome to Chat Doctor. I am Chat Doctor.  I have read your query in detail. Furthermore, I understand your concern. There is no harm in getting a tetanus injection, even if nail has just pierced the skin. Usually tetanus is spread by blood contact of contaminated item. So, chances are very less, but get a shot to be safe. This is my best advice for you based on available details. If you have any further query please ask me. Stay Healthy. ChatDoctor, MD
