When do you need a tetanus shot? Adults need a booster every 10 years, and sometimes sooner. Under the CDC’s wound management guidance, once your primary series is complete, a clean, minor cut needs a shot at 10 or more years since your last dose, and a puncture, bite, burn, or dirty wound needs one at 5 or more years. Never finished the series, or can’t remember? The CDC recommends a shot for any wound.
Tetanus shots are on the services list at our Covington clinic, and so are simple wound care and laceration repair. Every day, Saturday and Sunday included, the front door unlocks at 7 a.m. and stays that way until 7 p.m. That way a weekend cut or a Sunday nail doesn’t have to wait for Monday. If it’s a true emergency, though, call 911.
Three things worth knowing first:
- Rust isn’t the real culprit. Per the CDC’s Tetanus: Causes and How It Spreads, the spores live in soil, dust, and manure, so a garden-tool puncture matters as much as an old nail.
- Animal bites count. The CDC’s Dogs and Cats pages list a last tetanus shot more than 5 years back as a reason to get care after a dog bite, or after a cat bite or scratch.
- Td or Tdap can serve as your 10-year booster, and Tdap adds whooping cough protection, according to the CDC’s Types of Tetanus Vaccines page.
How often do you need a tetanus shot?
Adults need a tetanus booster every 10 years. The CDC’s Tetanus Vaccination page explains why the clock matters: “Vaccines that help protect against tetanus work well but protection decreases over time. People need a booster dose every 10 years to maintain protection.”
Kids build that protection in steps. The American Academy of Pediatrics lays out the schedule in its article Tetanus in Children: Symptoms, Treatment and Why the Vaccine Matters, “To be fully protected, children need five doses: at 2 months, 4 months, 6 months, 15-18 months and 4-6 years of age.” A Tdap dose follows at age 11 to 12, so ask your child’s pediatrician if you’re unsure where your kids stand. After that, adults stay on the 10-year rhythm, with one big exception: certain injuries move the deadline up.
When do you need a tetanus shot after a cut or other injury?
After an injury, your need for a tetanus shot depends on three things: whether you finished the primary vaccine series, how dirty or deep the wound is, and how long it’s been since your last dose. The CDC sorts wounds into two groups. Its guidance says “Clean and minor wounds don’t pose a major risk,” while dirty or major wounds move the window down to 5 years.
Here’s how the CDC’s Clinical Guidance for Wound Management to Prevent Tetanus plays out (updated September 8, 2026):
So what counts as dirty or major? Here’s what the CDC guidance lists:
- Penetrating or puncture wounds
- Wounds containing dirt, soil, feces, or saliva (e.g., animal or human bites)
- Wounds containing devitalized tissue, such as burns, compound fractures, crush injuries, frostbite, and necrotic or gangrenous wounds
Emergency physicians use the same 10-year starting point. The American College of Emergency Physicians page Cuts and Abrasions says, “A tetanus shot may be required if you have not had one within 10 years or if you are unsure of when you last had one.” If you’re unsure whether a cut needs closing too, our guide on how to know if you need stitches walks through the warning signs.
Do you need a tetanus shot after stepping on a nail?
Often, yes. A nail through the sole of a shoe is a puncture wound, and the CDC lists puncture wounds as dirty or major, so if you’ve completed your primary series, you’d want a booster when your last one was 5 or more years ago. MedlinePlus, run by the National Library of Medicine, has a page on Cuts and puncture wounds that says to contact your health care provider right away if “You step on a nail or other similar object.”
The rust itself isn’t what makes it risky. The CDC’s page Tetanus: Causes and How It Spreads states that “Spores of Clostridium tetani are common in the environment, including soil, dust, and manure.” McGill University’s Office for Science and Society, in Rust Doesn’t Give You Tetanus, puts it bluntly: “the relationship between rust and tetanus-causing bacteria is purely correlative, not causative.”
Around the Northshore, October often brings fall garden chores and yard cleanup. Pruning shears, rake tines, and bagged manure can all put you right in that soil. Fishing injuries count too. The MedlinePlus page on Fishhook removal says to contact your provider if you have a fishhook injury and your tetanus immunization isn’t up to date, or if you’re unsure.
Do you need a tetanus shot after a dog bite or cat scratch?
You might. Bites carry saliva, which the CDC lists as a dirty-wound contaminant. The CDC’s Dogs page on its Healthy Pets, Healthy People site lists five reasons to see a healthcare provider after a dog bite, and one of them applies when your last tetanus shot was more than 5 years ago. The other four cover deep or serious wounds, infection, and not knowing whether the dog has been vaccinated against rabies. The CDC’s Cats page uses the same 5-year line for cat bites and scratches.
For bleeding that won’t quit, the CDC’s Dogs page is clear: “Call 911 or your local emergency medical services immediately if you cannot stop the bleeding or you feel faint or weak.”
Kids get extra caution from pediatricians. The AAP’s Tetanus in Children article advises, “If your child has a wound that was in contact with soil, call your pediatrician right away.”
How long does a tetanus shot last?
A tetanus shot protects most fully vaccinated people for about 10 years. The CDC page Types of Tetanus Vaccines says, “They protect most people who are fully vaccinated against tetanus for 10 years.” That’s the reason a booster is due each decade, and the reason a dirty wound at year 6 or 7 can still mean another dose.
Tdap vs tetanus shot: which one will you get?
A tetanus shot for an adult is either Tdap or Td, and both protect against tetanus and diphtheria. The difference is whooping cough: Tdap covers it and Td doesn’t. Both are given to people 7 and older, and either one can serve as your 10-year booster. The CDC’s Types of Tetanus Vaccines page breaks them down this way:
- Tdap: Tetanus, diphtheria, and whooping cough
- Td: Tetanus and diphtheria
If you’ve never had a Tdap shot at all, the CDC’s Tdap Vaccine Information Statement says, “Adults who have never received Tdap should get a dose of Tdap.” It also recommends a dose during every pregnancy, preferably during the early part of the third trimester, to help protect the newborn from whooping cough. The CDC’s Vaccinating Pregnant Patients guidance for providers adds, “A patient should receive Tdap anytime during pregnancy if it’s indicated for wound care or during a community pertussis outbreak.”
Whooping cough made headlines in Louisiana in 2025. In a May 2025 update on measles and whooping cough, the Louisiana Department of Health counted 170 whooping cough cases so far that year and said, “Louisiana is on track to set a record high in 2025, exceeding the previous record of 214 cases reported in 2013.” In its earlier May 2025 whooping cough release, LDH added that people who may have close contact with young babies should talk to their healthcare provider about their vaccine history and whether they should receive a pertussis vaccine. That group can include new grandparents.
What are the side effects of a tetanus shot?
Tetanus shot side effects are usually mild, and pain, redness, or swelling where the shot went in tops the CDC’s list. The CDC’s Tetanus Vaccination page also says most people who get a vaccine that helps protect against tetanus don’t have any serious problems. For Td and Tdap, it lists these mild problems:
- Pain, redness, or swelling where the vaccine provider gave the vaccine
- Mild fever
- Headache
- Feeling tired
- Nausea, vomiting, diarrhea, or stomachache
The same page adds, “These are usually mild and go away on their own within a few days, but serious reactions are possible.” The CDC’s Diphtheria, Tetanus, and Pertussis Vaccine Safety page notes that “Severe allergic reactions following vaccination are rare, but can be life threatening.” The Tdap Vaccine Information Statement says that if you see signs of a severe allergic reaction, such as hives, swelling of the face and throat, difficulty breathing, a fast heartbeat, dizziness, or weakness, “call 9-1-1 and get the person to the nearest hospital.”
What are the symptoms of tetanus, and when is it an emergency?
Tetanus symptoms usually show up between 3 and 21 days after exposure, and the CDC says the average is 8 days. The CDC’s About Tetanus page explains that the first sign is most commonly spasms of the jaw muscles, better known as lockjaw. Other symptoms it lists include trouble swallowing, sudden, involuntary muscle spasms, often in the stomach, painful muscle stiffness all over the body, headache, fever and sweating, and changes in blood pressure and heart rate. Seizures, which the CDC describes as jerking or staring, are on the list too.
Tetanus is rare in the United States. According to the CDC’s Tetanus Surveillance and Trends page, “Since 2010, there have been fewer than 40 reported cases each year.” Most cases are in people who never got the vaccine, didn’t finish the series, or fell behind on their 10-year boosters. It is serious when it happens, though. The CDC’s About Tetanus page says 1 in 10 cases in the United States are fatal, and that tetanus “requires immediate treatment in a hospital.”
That’s an emergency room situation, not an urgent care one. If you or someone in your family has jaw cramping, muscle spasms, or trouble swallowing after a wound, get to the closest ER or call 911. Preventing tetanus with a timely shot is the part we can help with.
Can you get a tetanus shot at urgent care near me?
Yes. Typing urgent care near me or tetanus shot near me after a cut, bite, or puncture somewhere in St. Tammany Parish? Our clinic on Hwy 25 in Covington offers tetanus shots. The listing on our urgent care services page covers evaluating the injury, reviewing your immunizations, and a plan of care. Weekday or weekend, you’re welcome to walk right in. If bleeding won’t stop, or you feel faint or weak, call 911 instead.
Wondering where can I get a tetanus shot that also handles the cut itself? In our view, the best urgent care near Folsom or Covington for a wound is one that’s open when the injury happens (weekends too), can clean and close the wound, and can check whether you need a tetanus shot. Our Covington walk-in urgent care clinic does all of that, and our services list includes on-site X-rays for injury and illness when a provider wants a closer look.
You’ll find us just north of downtown Covington, off the Hwy 190 and Hwy 25 junction, close to Folsom and Franklinton. We welcome patients from Abita Springs, Madisonville, and Mandeville as well. The clinic grew out of Jennifer Duncan’s 25-plus years in emergency and urgent care medicine; her full credentials are APRN, MSN, FNP-C.
Without insurance, plan on $130 for a self-pay office visit; that price covers exams and referrals, plus any prescriptions written at the visit. The vaccine doesn’t have its own posted price on our pricing and insurance page, so dial (985) 400-5370 before heading over. Insured patients are covered too: most major plans work here, and our staff bills your insurance company directly. The CDC’s How to Pay for Vaccines page notes that Marketplace plans and most other private insurance plans must cover certain vaccines without a copayment or coinsurance from an in-network provider, and that Medicare Part B pays for vaccines directly related to the treatment of an injury, such as tetanus.
Can’t remember your last tetanus shot?
Lots of people can’t. Louisiana keeps an immunization information system called LINKS, and the Louisiana Department of Health’s Request Vaccination Records page says, “All vaccinators in Louisiana are required to enter vaccines in the LINKS database.” The same page says signing up for LA MyIR lets Louisiana residents “access, review, and print your official vaccination records without requesting them from a doctor.” Still not sure? Come in anyway. An unknown history is one of the situations where the CDC already recommends a shot after a wound.
Frequently asked questions
Maybe. The CDC treats clean, minor wounds as low risk, so a shot is recommended only if your last dose was 10 or more years ago, you never finished the primary series, or you don’t know your history. Animal scratches are a different story, since the CDC’s cat guidance uses the 5-year mark for scratches as well as bites.
No. The CDC says people don’t spread tetanus bacteria to other people. You get tetanus when spores from the environment enter the body through broken skin, usually through an injury.
Yes. The CDC recommends a Tdap dose during every pregnancy, preferably early in the third trimester, and its guidance for providers says Tdap should be given anytime during pregnancy if it is needed for wound care. Talk with your OB or provider about timing.
Usually. The CDC says Marketplace plans and most private plans must cover certain vaccines without a copay or coinsurance from an in-network provider, and it lists tetanus, diphtheria, and pertussis among the vaccines usually covered by health insurance. Medicare Part B pays for vaccines tied to treating an injury, such as tetanus. Check your own plan for details.
We haven’t posted a vaccine price online. Self-pay visits are $130, covering the exam, referrals, and medication prescribing, so call (985) 400-5370 and our staff can quote the out-of-pocket cost before you come in.
Not necessarily. The CDC says a previous tetanus infection may not provide enough immunity to prevent reinfection, so staying current on boosters and getting wounds checked still matters.
