You can eat eggs after receiving a tetanus shot, as eggs do not affect the efficacy of the tetanus vaccine. It is advised not to consume alcohol before and after the tetanus injection to avoid affecting the therapeutic effects and interfering with the skin test results. The purpose of the tetanus shot is to prevent infection from Clostridium tetani, an anaerobic bacterium. If the wound is in an anaerobic environment or heavily contaminated, it facilitates the colonization of Clostridium tetani. After receiving a tetanus shot, it is recommended to continue thorough wound cleaning and dressing changes, avoid alcohol, rest, and not to rub the injection site.
