When Was the Last Time You Had a Tetanus Booster?

You’re unlikely to think about tetanus until you step on a rusty nail or get a deep cut while gardening. But waiting for an accident isn't the best way to manage your health. Tetanus is a serious bacterial infection, and staying up to date on your vaccines is the only reliable way to prevent it.

At Palm Desert Urgent Care, in Palm Desert, CA, Manzoor Kazi, MD, provides wound care and sees many patients who don’t remember the date of their last tetanus shot. 

Here’s what he tells patients about the importance of keeping up with these vaccines.

Tetanus 101

Tetanus is caused by a bacterium called Clostridium tetani. These spores live in soil, dust, and manure. When you get a puncture wound, cut, or scrape, bacteria can enter your body and produce toxins. This toxin attacks your nervous system, causing painful muscle stiffness and spasms.

Tetanus is often called "lockjaw" because the muscle spasms often start in the jaw and neck. It can make swallowing difficult and even lead to breathing problems. Unlike many other vaccine-preventable diseases, tetanus isn't contagious. You can't catch it from someone else, so your personal immunity is your only line of defense.

When you need a tetanus shot

Most adults need a tetanus booster vaccine every 10 years to maintain immunity. The standard vaccine for adults is the Tdap shot, which protects against tetanus, diphtheria, and pertussis (whooping cough). If you haven't received a Tdap vaccine before, you should get one in place of your next regular Td booster.

You might need a booster sooner than 10 years if you experience a deep or dirty wound. If your wound involves soil, rust, feces, or saliva, and it has been more than five years since your last shot, medical guidelines recommend getting a booster immediately. Getting the vaccine within 48 hours of an injury offers the best protection against infection.

What to do after suffering a wound

If you get a cut or puncture wound, take immediate action to reduce your risk of complications. Clean the area with mild soap and running water as soon as possible. Don't leave dirt or debris in the wound, as this creates an environment where bacteria thrive.

• Clean the wound gently with water.
• Apply an antibiotic ointment to keep the area moist.
• Cover the injury with a clean bandage to protect it from dirt.
• Monitor the area for signs of infection, such as redness, swelling, or warmth.

If you aren't sure about your vaccine history or if the wound is deep, call Palm Desert Urgent Care or book a same-day appointment online.
