A small wound may seem harmless, a scrape from gardening, a minor cut on a rusty surface, or even a bite from a pet. Often, we clean it, slap on a bandage, and carry on with our day, never giving it a second thought. But beneath that seemingly trivial injury, an unseen danger could be lurking. Tetanus, a fatal condition caused by Clostridium tetani, thrives in such scenarios.
To understand why taking a tetanus injection after an injury is crucial, what happens if you don’t, and how you can protect yourself from this silent but deadly threat, OnlyMyHealth team spoke to Dr Kiran Dhake, Wellness Physician and Sonologist, Mumbai.
He says, “It is a well-known fact, and it goes without saying that an individual who is injured must take the tetanus (TT) vaccine.” This simple step could be the difference between a quick recovery and a life-altering, or even life-ending, battle with an entirely preventable condition.
The Threat of Tetanus
Tetanus is a serious and potentially fatal condition caused by the bacterium Clostridium tetani. These bacteria are commonly found in soil, dust, and animal faeces. If they enter the body through an open wound, they release a toxin called tetanospasmin, which targets the nervous system. Dr Dhake elaborates, “When the bacterium enters the body through an open wound, it can produce a toxin known as tetanospasmin, which affects the nervous system. This toxin interferes with normal muscle control, leading to painful muscle stiffness and spasms, often beginning in the jaw and neck (commonly referred to as ‘lockjaw’).”

How Tetanus Progresses
The symptoms of tetanus typically appear within 3 to 21 days of infection, often around the 7-day mark.
Early Symptoms
- Muscle stiffness near the wound site
- Lockjaw (trismus), making it hard to open the mouth
- Difficulty swallowing
Advanced Symptoms
- Severe muscle spasms in the neck, chest, and abdomen
- Arching of the back (opisthotonos)
- Difficulty breathing due to chest muscle and diaphragm spasms
Without immediate medical intervention, tetanus can lead to severe complications such as respiratory failure, fractures due to intense spasms, or even death.
Complications of Untreated Tetanus
If left untreated, tetanus can spiral into catastrophic health events, including:
- Respiratory failure caused by breathing muscle spasms
- Severe dehydration due to swallowing difficulties
- Heart complications or secondary infections like pneumonia
- A high mortality rate, even with treatment

Prevention Through Tetanus Vaccination
A tetanus injection acts as a shield against the life-threatening effects of this condition. Dr Dhake emphasises, “Receiving a tetanus injection shortly after an injury is a vital preventative measure, as it helps neutralise the toxin and significantly reduces the risk of infection.”
When is a tetanus shot essential?
- For dirty, deep, or puncture wounds (e.g., those caused by nails or animal bites)
- If the last tetanus booster was over 5 years ago
- For minor wounds in fully vaccinated individuals, a booster may not be necessary
What Happens if You Delay?
If you miss the recommended timeframe for a tetanus shot (ideally within 48 hours, though it may still offer protection within 7 days), watch for symptoms. Seek immediate medical attention if signs of tetanus appear. Doctors may administer tetanus immunoglobulin (TIG) alongside the vaccine to neutralise the toxin and manage the condition.
The Importance of Regular Vaccination
Prevention is key since there is no cure once the toxin binds to nerve structures. Tetanus boosters are recommended every 10 years to maintain immunity. For individuals exposed to environments with frequent cuts, contamination from soil or rust, or animal waste, staying updated on tetanus vaccinations is especially vital.
Dr Dhake aptly concludes, “By keeping up to date with tetanus vaccinations, it is ensured that the body remains prepared to fight off the bacterium Clostridium tetani should an individual sustain an injury that puts life at risk.”
Conclusion
Tetanus is not a condition to be taken lightly. Ignoring a tetanus shot after an injury could result in life-threatening complications. Regular vaccinations and timely boosters are simple yet essential steps to ensure your safety and health. Don’t wait for the worst—act now to protect yourself.
