Why do people need a tetnus?

People need a tetanus vaccine to protect against tetanus, a serious bacterial infection caused by Clostridium tetani, which can lead to muscle stiffness and severe spasms. The bacteria often enter the body through wounds or cuts, especially in unvaccinated individuals. Vaccination helps build immunity and is crucial for preventing potentially life-threatening complications. Regular booster shots are recommended every 10 years to maintain protection.
