The tetanus shot is divided into tetanus antitoxin and tetanus immunoglobulin, the price of these two differs greatly, a tetanus antitoxin is basically about 10 yuan, tetanus immunoglobulin more for about 200 yuan. The price difference between tetanus injection and tetanus immunoglobulin is also great, but there is basically no difference in efficacy, only in the population for which they are used. When a patient with a traumatic injury enters the emergency department of a local hospital, a tetanus shot is recommended. The tetanus shot comes from the horse’s serum, which is a foreign substance to the human body, and a few people have allergic reactions to the tetanus shot. If the skin test results are negative, tetanus antitoxin can be injected. If the skin test is positive, intramuscular tetanus immunoglobulin is recommended to reduce the likelihood of an allergic reaction. Whether it is antitoxin or immunoglobulin, it is recommended to stay for 15 minutes after the injection to observe any physical discomfort.
