From the Guidelines
For a patient who stepped on a dirty rake with their last tetanus vaccination 10 years ago, a tetanus booster is recommended. The patient should receive a single dose of Td (tetanus and diphtheria) or Tdap (tetanus, diphtheria, and acellular pertussis) vaccine. Tdap is preferred if the patient has not previously received it as an adult. The standard dose is 0.5 mL administered intramuscularly, typically in the deltoid muscle. No tetanus immune globulin (TIG) is needed in this case since the patient has a history of completed primary vaccination series, even though the last dose was at the 10-year mark. This recommendation is based on the understanding that immunity to tetanus wanes over time, but individuals with a complete primary series maintain some level of protection, as indicated by the most recent guidelines 1. The booster stimulates the immune system to produce protective antibodies against tetanus toxin, which can cause muscle rigidity and spasms if infection occurs through contaminated wounds. The wound should also be thoroughly cleaned with soap and water, and any visible debris should be removed to reduce the risk of infection. According to the updated recommendations of the Advisory Committee on Immunization Practices (ACIP) in 2020, either Td or Tdap can be used for booster doses, increasing provider flexibility 1. Given the patient's situation, where the wound is contaminated with dirt from the rake, the guidelines suggest a booster is appropriate if the patient has not received tetanus toxoid during the preceding 5 years for all other wounds, but since the patient is exactly at the 10-year mark, and considering the wound type, the recommendation aligns with the need for a booster 1. Thus, the patient should receive the booster to ensure protection against tetanus.
From the FDA Drug Label
For active tetanus immunization in wound management of patients 7 years of age and older, a preparation containing tetanus and diphtheria toxoids is preferred instead of single-antigen tetanus toxoid to enhance diphtheria protection. The need for active immunization with a tetanus toxoid-containing preparation, with or without passive immunization with Tetanus Immune Globulin (TIG) (Human) depends on both the condition of the wound and the patient's vaccination history.

- Such as, but not limited to, wounds contaminated with dirt, puncture wounds and traumatic wounds ‡ Yes, if >10 years since last dose.
The patient stepped on a dirty rake, which is considered a wound contaminated with dirt. According to the table, since it has been 10 years since the patient's last tetanus vaccination, the recommended tetanus prophylaxis is yes for Td (tetanus and diphtheria toxoids). 2
From the Research
Tetanus Prophylaxis Recommendations
- The patient stepped on a dirty rake with their last tetanus vaccination 10 years ago, which increases the risk of tetanus infection.
- According to general guidelines, a tetanus booster is recommended every 10 years, but in cases of dirty or contaminated wounds, a booster may be recommended sooner 3.
- However, the provided studies do not directly address the specific scenario of a patient stepping on a dirty rake with their last tetanus vaccination 10 years ago.
Study Findings
- A study published in 2010 found that administering a Tdap vaccine less than 2 years after a previous tetanus vaccination is safe 3.
- Another study published in 2020 evaluated the cost-effectiveness of Tdap vaccination for adults aged 19 and older, but did not provide specific guidance on tetanus prophylaxis for patients with dirty wounds 4.
Tetanus Prophylaxis Guidance
- In general, the Centers for Disease Control and Prevention (CDC) recommends tetanus prophylaxis for patients with dirty or contaminated wounds if their last tetanus vaccination was more than 5 years ago.
- However, the provided studies do not offer specific guidance on this scenario, and the decision to administer a tetanus booster should be made on a case-by-case basis, taking into account the patient's individual risk factors and medical history.
