The time period for tetanus injections depends on the individual's vaccination history and current situation. For adults, a tetanus booster shot (Td or Tdap) is recommended every 10 years to maintain protection. This is consistent across multiple sources, including the Cleveland Clinic (https://my.clevelandclinic.org/health/drugs/24283-tetanus-shot), Piedmont Healthcare (https://www.piedmont.org/living-real-change/when-to-get-a-tetanus-shot-after-an-injury), and various other reputable sources cited above. Children require a different vaccination schedule, with multiple doses administered at different ages.
While the routine booster is every 10 years, additional considerations exist:
- Wounds: Individuals with deep, dirty wounds, or wounds with a high risk of tetanus infection may require a booster even if their last dose was within the 10-year timeframe. This is a clinical decision made by a healthcare provider, evaluating the wound's characteristics.
- Pregnancy: A Tdap booster is recommended during the third trimester of pregnancy, irrespective of the individual's vaccination history.

It's crucial to note that the time between exposure to tetanus bacteria and the onset of symptoms (incubation period) ranges from 3 to 21 days. (https://www.who.int/news-room/fact-sheets/detail/tetanus, https://www.buzzrx.com/blog/do-i-need-a-tetanus-shot-for-a-small-puncture) This is distinct from the time between tetanus vaccinations. The vaccine prevents the disease, not treating an existing infection.
In summary: While a routine tetanus booster is given every 10 years for adults, specific circumstances may necessitate earlier administration. Always consult a healthcare professional for personalized vaccination advice.
