Children in China generally have planned immunization, and if they have not completed the planned immunization, they need tetanus vaccination. If the planned immunization is completed, generally within two years of age is a booster injection, before 6-7 years of age children occur injuries, bumps, as long as a tetanus vaccine to strengthen the level of antibodies in the body can be. Generally there will be effective antibodies within 10 years after the age of 6-7, so for small wounds there is no need for tetanus antitoxin. If there are serious deep wounds with severe contamination, such as severe fractures or internal organ damage, it is better to have another tetanus antitoxin shot to strengthen the tetanus antibody level, which is safer. Therefore, the need for another tetanus injection should be judged on a case-by-case basis.
