Tetanus is a potentially life-threatening bacterial infection caused by Clostridium tetani, which enters the body through open wounds or cuts. To prevent tetanus, individuals receive tetanus vaccinations, typically as part of a combined vaccine called the Tdap or DTaP (for children) that also protects against diphtheria and pertussis. The question of how long does a tetanus shot last is a common one, and the answer depends on the type of vaccine received:

Tdap Vaccine: The Tdap vaccine provides protection against tetanus, diphtheria, and pertussis. After the initial series of shots during childhood, a Tdap booster is recommended every ten years. This means the vaccine can provide protection against tetanus for a decade.

DTaP Vaccine (for Children): Children receive a series of DTaP shots during their early years. A booster dose is recommended at age 11-12, and further boosters are administered every ten years.

It's crucial to stay up-to-date with tetanus vaccinations to ensure continued protection. In cases of wounds or injuries that could expose you to tetanus, a healthcare provider may recommend a tetanus shot if it has been more than five years since your last booster. Tetanus prevention through vaccination is vital, as tetanus is a serious and potentially fatal disease.
