Patient's question:
DTaP is tetanus?Doctor's answer:
DTaP is not tetanus; DTaP can prevent tetanus, and their mechanisms of action are different. DTaP is different from tetanus. After receiving the DTaP vaccine, if an injury occurs, especially a contaminated injury, tetanus antitoxin still needs to be administered, as their immune mechanisms are different. DTaP contains tetanus, which is active immunity. Generally, the immune effect can last for 10 years, meaning that within this 10-year period, there is no need to worry about tetanus.
