A tetanus shot generally provides protection for about 10 years in most people. After the initial childhood vaccination series, booster shots are recommended every 10 years to maintain immunity against tetanus
. Some research suggests that immunity could last longer, potentially up to 30 years after completing the full childhood series, but current public health guidelines still recommend a booster every 10 years for adults
. In cases of injury, if it has been more than 5 or 10 years since the last tetanus shot (depending on the wound's severity), a booster may be recommended sooner to ensure protection
Summary:
- Initial series in childhood plus boosters every 10 years for adults.
- Protection lasts roughly 10 years per shot.
- Some evidence suggests possible longer immunity, but 10-year boosters remain standard.
- For certain wounds, a booster may be given if more than 5 years have passed since the last shot.
This schedule helps maintain effective immunity against tetanus, a serious bacterial infection
