Tetanus shots can be administered at the emergency department of a regular public hospital. Tetanus toxoid requires a skin test, and if the result is positive indicating an allergy, it cannot be administered; tetanus immunoglobulin does not require a skin test and can be used directly. Alcohol consumption should be avoided before receiving a tetanus shot, as it can affect the results of the skin test, leading to inaccurate indications for the tetanus injection, and impacting its effectiveness.
