The injection of tetanus shots is performed in the emergency department of regular hospitals.

Tetanus shots are divided into tetanus toxoid, which requires a skin test, and tetanus immunoglobulin, which does not require a skin test. If the skin test for tetanus toxoid is positive, indicating an allergy, it cannot be injected, and must be replaced with the slightly more expensive tetanus immunoglobulin. It is generally recommended to administer the injection within 24 hours after injury to prevent infection by Clostridium tetani. Clostridium tetani is an anaerobic bacterium. It is necessary to administer tetanus treatment for injuries that are deep, in anaerobic conditions, contaminated, heavily contaminated with soil, rust, open fractures, etc., since these conditions can be conducive to tetanus infection.

Is it necessary to get a tetanus shot?

Getting a tetanus shot is very necessary if a patient has had an injury or has wounds on the body. Without a tetanus shot, there might be a risk of tetanus infection. The main reason is due to the presence of tetanus bacillus spores in the natural environment, which could colonize within the wound if it's exposed. This can potentially lead to a tetanus infection. Severe cases can present with symptoms such as opisthotonos, breathing difficulties, suffocation, and could even lead to death. The tetanus shot involves injecting tetanus antitoxin into the patient's body, which is a form of passive immunity and can prevent some symptoms of tetanus infection.

How many years does the tetanus vaccine last?

Tetanus vaccines generally involve an active immunization process against tetanus with a complete immunization schedule, providing effective protection for up to ten years for those who have completed the full course of prevention. Typically, newborns must receive three doses of the DTP (diphtheria, tetanus, pertussis) vaccine, with the first dose administered at three months of age, followed by a dose each subsequent month, and booster shots at eighteen months or six years of age. If vaccinated, no further tetanus antitoxin or tetanus immunoglobulin injections are required for injuries incurred within ten years of vaccination. If no active immunization has been done and the wound is heavily contaminated, it is crucial to promptly administer tetanus antitoxin or tetanus immunoglobulin. A skin test must be performed before using tetanus antitoxin; if the test is strongly positive, immunoglobulin should be administered for preventive treatment.

What is the function of a tetanus shot?

The function of the tetanus shot is to activate the body's immune system to produce antibodies that can specifically bind to the tetanus toxin, preventing the toxin from binding with nerve cells and causing a toxic reaction that could lead to respiratory arrest, asphyxiation, and endanger life safety. Tetanus infection occurs when the Clostridium tetani bacteria enter the body through mucous membranes following an injury, producing toxins that affect certain muscle groups, such as the jaw and respiratory muscles, thus threatening life safety. Therefore, the role of the tetanus shot is to produce antibodies that bind to the tetanus toxin, preventing it from producing a toxic reaction with nerve cells. Thus, if some wounds are deep and heavily contaminated, it is essential to undergo anti-tetanus treatment.

When is the best time to get a tetanus shot?

Tetanus infection carries a certain mortality rate, with current statistics indicating that the death rate from tetanus infection can reach around 40%. Typically, tetanus is caused by an acute, specific infection resulting from the growth and reproduction of Clostridium tetani in human wounds, which produce toxins. Generally, it can only grow and reproduce in an anoxic environment, so it is most commonly found in soil, human and animal feces, and rust. For wounds, especially sharp and deep cuts, it is usually vital to administer a tetanus shot promptly. The choices generally are tetanus immunoglobulin or tetanus antitoxin, which have different half-lives; tetanus antitoxin generally lasts about three days, whereas tetanus immunoglobulin can last up to three weeks. Therefore, in the presence of high-risk infection factors, it is advisable to administer the injection as soon as possible, generally recommended within 24 hours.

Does tetanus infect others?

Tetanus occurs when wounds are contaminated by Clostridium tetani, which then proliferates and grows within the human body, ultimately causing tetanus. Generally, tetanus is not transmitted from person to person; it usually occurs when bacteria invade the body through external injuries or wounds. Additionally, newborns may contract tetanus through the birth canal during delivery. Therefore, for deep or large wounds, especially in heavily contaminated conditions, it is crucial to clean and possibly stitch the wounds promptly. If necessary, tetanus immune globulin injections and vaccinations against these bacteria can be administered to thoroughly prevent the occurrence of tetanus.
