Question

Is the DPT vaccine tetanus?

Answer

The DPT vaccine is not tetanus. The DPT vaccine can prevent tetanus, but their mechanisms of action are different. The DPT vaccine is not the same as the tetanus vaccine; after receiving the DPT vaccine, if an injury occurs, especially a contaminated one, it is still necessary to receive tetanus antitoxin. Their immune mechanisms are different. The DPT vaccine includes tetanus; this is active immunity, and its immune effect can last for 10 years, meaning that within 10 years, there is no need to worry about tetanus.
