Do I need a tetanus shot for a small puncture?

Tetanus, which is also known as lockjaw, is a serious but rare disease. People with this disease die about 20% of the time. Tetanus shots are a very good way to keep people from dying from tetanus. Because of the tetanus vaccine, this disease is rare in the US. Each year, only about 30 people get it.

But to keep yourself safe, you need to be up-to-date on your tetanus shots. You should get a booster shot every 10 years, or every 5 years if you get hurt.

Read on to learn more about tetanus, why people die from it, how to avoid it, and if you need a tetanus shot for a small puncture wound.


Tetanus is a very dangerous bacterial infection caused by Clostridium tetani, a microorganism that lives in dirt, soil, and feces. The bacteria get into the body through cuts, wounds, punctures, crush injuries, burns, or animal bites—anywhere that the skin is broken and exposed to soil or dirt.

Once the tetanus bacteria get into the body, they make poisons. The effect of the toxin is to mess with the nervous system, which makes muscles tighten and spasm. When tetanus is really bad, the muscle spasms can be strong enough to break bones. The painful tightening of the jaw muscles is called “lockjaw.” This makes it hard to open the mouth, breathe, and swallow. When tetanus is very bad, the toxins can make it so that the person can’t move and can’t breathe because their breathing muscles are also paralyzed.

Tetanus is now very rare in the United States because of a vaccine. When it does happen, though, tetanus is a serious infection that can be fatal.

Patients with tetanus are not contagious, which means that the disease does not spread from one person to another. Tetanus has no treatment. The best way to protect yourself from this dangerous infection is to get a tetanus shot. Most people who die from tetanus are not vaccinated.

Do I need a tetanus shot for a small puncture


Yes, you can get tetanus from any skin injury with a break in the skin, even a small hole in the skin. The bacteria that cause tetanus can get into your body through any cut or scrape, even small ones, especially if they look dirty or have been in the soil.


Yes, as was said above, the size of the wound doesn’t matter. Even small wounds can cause tetanus and other bacterial infections. The most likely way to get tetanus is from a puncture wound from something like a nail or a bite from an animal, like a dog.

If a nail pierces your skin, you should clean the wound with soap and water to keep it from getting infected. A small wound might be able to be fixed at home. But you should see a doctor if the wound gets more painful and red or if you have any other worries.

If it’s been more than 10 years since your last tetanus shot, you should talk to your doctor and get the right care, which may include a booster shot of the Td or Tdap vaccine.

How soon should you get a tetanus shot after a cut?

Many people want to know how quickly tetanus develops. The time between being exposed to tetanus and getting sick ranges from 3 to 21 days, with an average of 10 days.

But you need to move quickly. If you get hurt and think you might be at risk for tetanus, and you haven’t had a tetanus booster shot in the last 5 years, you should go to the emergency room within 24 hours.

What happens if you don’t get a tetanus shot after a cut?

Muscle spasms, usually in the jaw, are often the first sign of mild tetanus. When tetanus is moderate, the muscles in the neck, chest, back, and abdomen can spasm. When tetanus is very bad, the spasms can affect the muscles that help you breathe. This can make it hard to breathe or even kill you.

Tetanus can also cause fever, sweating, headaches, stiff muscles, seizures, a fast heart rate, and high blood pressure. These are signs and symptoms that happen when the body’s immune system reacts to an infection to fight it off.

If you have tetanus, you need to see a doctor right away. If you see any of the above signs in someone who has been hurt, call 911 right away or take them to the nearest emergency room.

CDC Recommendations for Tetanus Vaccinations

Everyone should get a tetanus shot, says the Centers for Disease Control and Prevention (CDC). There are four vaccines that can protect against tetanus. These shots also protect against bacterial diseases like diphtheria and whooping cough.

  • Tetanus and diphtheria (DT) vaccine
  • Diphtheria, tetanus, and whooping cough vaccine (DTaP)
  • Diphtheria and tetanus (Td) vaccine
  • Tetanus, diphtheria, and whooping cough vaccine (Tdap)

Babies and children under 7 get the DTaP and DT vaccines. Adults and older children get the Tdap and Td vaccines. The recommended tetanus set for children is 5 doses of DTaP at ages 2 months, 4 months, 6 months, 15–18 months, and 4-6 years, followed by a booster shot (6th dose) of DTaP at 11–12 years.

After getting the first set of tetanus shots as a child, you need a booster shot every 10 years or every 5 years if you get hurt.

If it’s been more than 10 years since your last tetanus shot, talk to your doctor about getting one. You only need a tetanus shot if you step on a rusty nail. All adults need to get a tetanus booster shot every 10 years to prevent this disease, which could kill them.
