Wounds that are exposed to air after injury are susceptible to bacterial infection. Although debridement surgery can remove most of the bacteria, tetanus antitoxin is still recommended for patients, including infants or children. However, tetanus immunity is not lifelong, meaning that one injection is not lifelong protection against the disease. Children are given tetanus vaccine, which contains a tetanus antitoxin component, at 3 months, 4 months and 6 months of age. It is recommended that infants and children consult an immunization station about injections within 24 hours of injury. Once infected with Clostridium tetani has a high mortality rate, it is recommended that patients with or without experience of tetanus vaccination should visit a hospital for vaccination.
