Tetanus is a word that often sends a shiver down the spine. The disease is known for its severe muscle spasms and lockjaw, which can be life-threatening if not treated quickly. Here are 8 essential things one must know about the tetanus vaccine.

Tetanus, also known as lockjaw, is caused by the bacteria. The bacteria is commonly found in soil, dust, and manure. When it enters the body, it releases a toxin that affects the nervous system and is potentially life-threatening.

The tetanus vaccine contains inactivated tetanus toxin (toxoid), which is harmless but prompts your immune system to produce antibodies. These antibodies provide protection by neutralising the toxin if you are exposed in the future.

Children should receive the DTaP vaccine (which also protects against diphtheria and pertussis) starting at two months old, while adults should get a booster shot (Td or Tdap).

Unlike some vaccines that offer lifetime immunity, the tetanus vaccine requires periodic boosters. Adults need a tetanus booster shot every ten years to maintain immunity. If exposed, it's recommended to get a booster if your last shot was more than five years ago

Most people experience only mild reactions such as soreness, redness, or swelling at the injection site. More severe reactions are rare but can include fever or muscle pain. The benefits of vaccination far outweigh the minimal risks.

The tetanus vaccine is often combined with diphtheria and pertussis vaccines (as DTaP or Tdap) to provide comprehensive protection against these diseases. This combination is convenient and reduces the number of shots needed.

If you miss your scheduled booster shot, you should get it as soon as possible. There’s no need to start the entire vaccination series again; a single booster will suffice to maintain protection.

Research continues to support the efficacy and safety of the tetanus vaccine. A study published in the journal Vaccine highlighted that the Tdap vaccine not only provides immunity but also has a very low incidence of adverse effects
