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.
Tetanus is characterised by:
Without treatment, tetanus can lead to serious complications, including fractures, respiratory failure, and even death.
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:
Yes, the tetanus vaccine is considered very safe. Most people experience only mild side effects, such as:
Severe side effects are rare, and the benefits of vaccination far outweigh the risks.
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.
