How much does a tetanus shot cost approximately?

Tetanus is a disease caused by infection of the skin or mucosa with Clostridium tetani and the release of toxins. The cause of tetanus is infection with Clostridium tetani. Symptoms of tetanus include difficulty opening the mouth, retraction of the corners of the mouth, stiffness of the neck, opisthotonus, cyanosis of the face, and difficulty breathing. How much does a tetanus shot cost? Let's take a look.

Generally speaking, the price of tetanus antitoxin is relatively cheap, costing only a few yuan on the market, generally not exceeding ten yuan. The so-called tetanus antitoxin is mainly extracted from horse serum and is prone to allergic reactions. Therefore, a skin test needs to be performed before injection. If there is no allergic reaction after the skin test, injection can be performed. Generally speaking, if a newborn experiences an allergic reaction when receiving a tetanus antitoxin injection, it is recommended to perform desensitization injection in 2 to 3 doses.

Compared to tetanus antitoxin, the price of tetanus immunoglobulin is relatively expensive, generally around 100 yuan. Tetanus immunoglobulin is extracted directly from human serum, so it can be injected directly without a skin test. Before injection, you can choose the appropriate method for injection based on the doctor's advice to achieve a more ideal effect.

For those who have received the full course of tetanus toxoid vaccine prevention, there is no need to reinject tetanus antitoxin or receive tetanus toxoid vaccine again for trauma within 5 to 10 years after the last injection. If it exceeds 5 to 10 years, a booster injection of tetanus toxoid vaccine can be given after injury, but it is not necessary to inject tetanus antitoxin or tetanus immunoglobulin.

The incubation period of tetanus infection is mostly 1 to 2 weeks. According to its pathogenesis, the application of tetanus antitoxin within 24 hours or even slightly later after injury can still play a preventive role. Clinically, it is emphasized to use it as early as possible, but as long as it is not onset and used within two weeks, it should be considered as having a preventive effect.

The antibodies brought by passive immunity to the body only last for 2 to 3 weeks, and the antibody level decreases thereafter, and the body is no longer protected. Therefore, using tetanus antitoxin or immunoglobulin once does not provide lasting immunity. Long-lasting immunity depends on the active immunity produced by the tetanus toxoid vaccine in the body.
