As we age, keeping up with vaccinations becomes increasingly important. One of the key vaccines that older adults should consider is the tetanus jab, which protects against a serious and potentially life-threatening bacterial infection. Many people wonder, how long does a tetanus jab last, and whether they still need boosters in later life.

At Midnight Pharmacy, we’re committed to helping patients stay informed about their vaccinations and ensuring they receive the necessary protection. In this guide, we’ll explore tetanus protection for older adults, when a booster might be needed, and how to stay up to date with your vaccinations.

What Is Tetanus and Why Is It Dangerous?

Tetanus is a bacterial infection caused by Clostridium tetani, a type of bacteria commonly found in soil, dust, and animal manure. Unlike many infectious diseases, tetanus doesn’t spread from person to person but enters the body through wounds, cuts, or punctures, such as stepping on a rusty nail or being scratched by a contaminated object.

Once inside the body, the bacteria produce a powerful toxin that affects the nervous system, leading to severe muscle stiffness and spasms. If left untreated, tetanus can cause life-threatening complications, including breathing difficulties, seizures, and even death. Fortunately, vaccination provides excellent protection against tetanus, but the immunity it offers doesn’t last forever.

How Long Does a Tetanus Jab Last?

A full childhood vaccination course against tetanus provides strong immunity, but it does not offer lifelong protection. In the UK, the standard NHS tetanus immunisation schedule includes:

Five doses given during childhood and adolescence, typically as part of the DTP (diphtheria, tetanus, and polio) vaccine.

A booster every 10 years if required, particularly for those at higher risk of exposure.

For most people, the five-dose childhood course offers long-term protection, but some individuals—especially older adults who may not remember their last tetanus jab—may need a booster for continued immunity.

Should Over-60s Get a Tetanus Booster?

For many people over 60, it’s been decades since their last tetanus jab, and immunity may have weakened. Whether or not a booster is needed depends on:

1. Your Vaccination History

If you received all five doses of the tetanus vaccine as part of the standard childhood immunisation schedule, you may not need routine boosters. However, if you’re unsure of your vaccination history or you missed some doses, a booster may be recommended to ensure full protection.

2. Your Risk of Exposure to Tetanus

Older adults who engage in activities that increase their risk of injury should consider getting a booster. This includes:

Gardening – Soil, compost, and plant matter can harbour tetanus bacteria.

Outdoor activities – Hiking, fishing, and farming can expose you to contaminated environments.

Minor injuries – Even a small cut or scrape, particularly from metal objects or animal bites, can pose a tetanus risk.

3. Emergency Situations and Injuries

If you suffer a deep or dirty wound and haven’t had a tetanus booster in the last 10 years, you may need an urgent tetanus shot. In some cases, a tetanus immunoglobulin injection may also be required if the wound is high-risk and your vaccination status is unclear.

What Happens If an Older Adult Gets Tetanus?

Although rare in the UK due to vaccination, tetanus can be severe in older adults, particularly if the infection spreads before treatment begins. Common symptoms include:

• – Stiffness in the jaw and neck muscles (also known as “lockjaw”)
• – Painful muscle spasms that can make breathing difficult
• – Difficulty swallowing and speaking
• – High fever and sweating
• – Seizures and convulsions in severe cases

For those over 60, weakened immune systems and underlying health conditions may make recovery more difficult. That’s why prevention through vaccination is the best approach.

Additionally, for those travelling to regions with limited medical facilities or higher risks of injury, ensuring your tetanus vaccination is up to date is an essential part of travel health preparation.

How to Check If You Need a Tetanus Booster

If you’re unsure when you last had a tetanus jab, checking your vaccination record is the best place to start. Your GP or pharmacist can help determine whether a booster is necessary based on your medical history.

At Midnight Pharmacy, we offer tetanus booster vaccinations, along with expert advice on whether you need one based on your individual risk factors. If you frequently engage in outdoor activities or haven’t had a booster in over 10 years, it’s worth getting updated protection.

Where Can You Get a Tetanus Booster?

Tetanus boosters are available at:

Your GP surgery – If you need a jab due to an injury, your GP may offer a booster.

Pharmacies – Many pharmacies, including Midnight Pharmacy, provide private tetanus boosters without the need for a GP appointment.

Hospitals or walk-in clinics – If you’ve had a serious wound, you may be given a tetanus shot as part of emergency care.

Protecting Yourself Against Tetanus in Later Life

Tetanus is a serious but preventable disease, and for older adults, staying up to date with vaccinations is crucial. While those who have completed the five-dose childhood course may have long-term immunity, a booster is often recommended every 10 years, particularly for those at risk of injury or infection.

At Midnight Pharmacy, we provide tetanus boosters and expert advice to help ensure you stay protected. If you’re unsure about your vaccination status or need a booster for travel, outdoor activities, or after an injury, contact us today to arrange an appointment. Keeping up with your tetanus vaccination is a simple but essential step in staying healthy and protected at any age.
