Tetanus Vaccine
Tetanus, commonly known as “lockjaw,” is a potentially life-threatening disease caused by a toxin produced by the bacteria Clostridium tetani. These bacteria are often found in soil, dust, and animal feces. When the bacteria enter the body through cuts or wounds, they can produce a toxin that affects the nervous system, leading to severe muscle stiffness and spasms. Fortunately, the tetanus vaccine is a safe and effective way to protect against this serious illness.

What is Tetanus?
Tetanus is characterised by:
- Stiffness of the jaw and neck muscles: This can make it difficult to open the mouth or swallow.
- Muscle spasms: These spasms can occur throughout the body, particularly in the back and abdomen.
- Pain and discomfort: The muscle contractions can be extremely painful.

How Does the Tetanus Vaccine Work?
The tetanus vaccine works by stimulating the immune system to produce antibodies against the tetanus toxin. This means that if a person is exposed to the bacteria in the future, their immune system will be prepared to fight off the infection. In South Africa, the tetanus vaccine is usually given in combination with vaccines for diphtheria and pertussis (whooping cough), known as the DTPa vaccine. The vaccine schedule includes:
- Three doses during infancy, usually at 6 weeks, 10 weeks, and 14 weeks of age.
- A booster dose at around 18 months and again at 6 years of age.
- Additional booster doses are recommended every 10 years for adults.

Why is the Tetanus Vaccine Important?
- Prevents Severe Illness: The vaccine is highly effective at preventing tetanus, which can cause severe and life-threatening complications.
- Community Health: High vaccination coverage in the community helps protect everyone, especially those who are unable to be vaccinated due to specific medical conditions.
- Promotes Awareness: Vaccination programs also educate communities about the importance of proper wound care and hygiene, which can further reduce the risk of tetanus infections.

Is the Tetanus Vaccine Safe?
Yes, the tetanus vaccine is considered very safe. Most people experience only mild side effects, such as:
- Soreness or redness at the injection site
- Mild fever
- Fatigue

Common Misconceptions
Some people may think that tetanus is no longer a concern or that it only affects certain populations. However, tetanus remains a risk, especially in regions where vaccination rates are low or among individuals who have not kept up with their booster shots. It is also important to remember that tetanus can occur after injuries that may not seem serious, such as cuts, scrapes, or puncture wounds. Keeping up with vaccinations is crucial, even for minor injuries.
