It's not recommended to take a bath immediately after receiving a tetanus shot. First, the wound requiring a tetanus shot may either be deep, heavily contaminated, or relatively large. After receiving a tetanus shot in the buttocks or the deltoid muscle of the upper arm, it is essential to enhance wound dressing changes and keep the wound dry, which is why bathing is not advised. If it's just a simple tetanus injection site, it can generally be exposed to water a few hours later. However, other wounds on the body should be kept dry. Therefore, it is better to take a bath when wounds on other parts of the body have healed well to avoid worsening infections and delaying healing.
