Prevention

You can easily prevent tetanus by being immunized against the toxin. Almost all cases of tetanus occur in people who've never been immunized or who haven't had a tetanus booster shot within the preceding 10 years.

The vaccine
The tetanus vaccine usually is given to children as part of the diphtheria and tetanus toxoids and pertussis (DTP) shot. This vaccination provides protection against three diseases: diphtheria (a throat and respiratory infection), pertussis (whooping cough) and tetanus. The latest version of this immunization is known as the diphtheria and tetanus toxoids and acellular pertussis (DTaP) vaccine.

The DTaP vaccine consists of a series of five shots, typically administered in the arm or thigh and given to children at ages:

• 2 months
• 4 months
• 6 months
• 15 to 18 months
• 4 to 6 years

The booster
It's recommended that adolescents get a booster shot between the ages of 11 and 18, and that adults receive a routine tetanus booster shot every 10 years. If you're traveling internationally, it's a good idea to have up-to-date immunity against tetanus because tetanus may be more common where you're visiting, especially if you're traveling to a developing country. If you receive a deep or dirty wound and it has been more than five years since your last booster shot, get another booster shot.

A booster of the tetanus vaccine is typically given in combination with a booster of diphtheria vaccine. Recently, pertussis vaccine has been added to this routine combination immunization to ensure that adults and adolescents are fully protected against pertussis. This combination vaccine is referred to as Tdap, and it's approved for use in teens and adults. In order to stay up-to-date with all of your vaccinations, request that your doctor review your vaccination status on a regular basis.

Having had a tetanus infection doesn't provide immunity. Following recommendations for vaccinations is necessary to prevent recurrence of tetanus. If you were never vaccinated against tetanus as a child, see your doctor about getting the Tdap vaccine. You can't get a tetanus infection from the vaccine.

Taking care of a wound
If you have a wound, these steps will help prevent you from contracting tetanus:

• Keep the wound clean. Rinse thoroughly with clean water. Clean the wound and the area around it with soap and a washcloth. If debris is embedded in a wound, see your doctor.
• Consider the source. Puncture wounds or other deep cuts, animal bites or particularly dirty wounds may put you at increased risk of tetanus infection. Call your doctor if the wound is deep and dirty, and particularly if you're unsure of your immunization status. Your doctor may need to clean the wound, prescribe an antibiotic and give you a booster shot of the tetanus toxoid vaccine. If you've previously been immunized, your body should quickly make the needed antibodies to protect you against tetanus.
• Use an antibiotic. After you clean the wound, apply a thin layer of an antibiotic cream or ointment, such as the multi-ingredient antibiotics Neosporin or Polysporin. These antibiotics won't make the wound heal faster, but they can discourage bacterial growth and infection and may allow your body to close the wound more efficiently. Certain ingredients in some ointments can cause a mild rash in some people. If a rash appears, stop using the ointment.
• Cover the wound. Exposure to the air may speed healing, but bandages can help keep the wound clean and keep harmful bacteria out. Blisters that are draining are vulnerable; keep them covered until a scab forms.
• Change the dressing. Applying a new dressing at least once a day or whenever the dressing becomes wet or dirty may help prevent infection. If you're allergic to the adhesive used in most bandages, switch to adhesive-free dressings or sterile gauze and paper tape.
