I was just rusting and accidentally broke a small hole. Do you need a tetanus needle
Tetanus is a kind of anaerobic bacteria. The principle of anaerobic bacteria is that it is easy to grow in an environment without oxygen. Small superficial wounds like you and air contact are an oxygen enriched environment, so you won't need tetanus needles. It's better to disinfect with hydrogen peroxide.
Accidentally made rust and cut a small hole. Now in this situation, the wound is not big and there is no infection. You can not break the cold vaccine. If the wound is deep and you need to break the cold vaccine, pay attention to avoid wound infection. Don't touch the wound with water and disinfect it with Iodophor.
If you accidentally break a small hole when contacting rust, it is recommended to go to the hospital for tetanus injection in time for the sake of safety. Before tetanus injection, you can wipe the wound with alcohol or iodophor first, and flushing can play the role of anti-inflammatory disinfection.
