Tetanus toxoid is a vaccine consisting of growth products of Clostridium tetani treated with formaldehyde serving as an active immunising agent. Hence it is weakened germs. The first tetanus toxoid (inactivated toxin) was produced in 1924 and was used successfully to prevent tetanus in the armed services during World War II. In the mid-1940s, tetanus vaccine was combined with diphtheria toxoid and inactivated pertussis vaccine to make the combination DTP vaccine for routine childhood immunization.

Immunization for Tetanus:
1. Correct Answer: Option C - Weakened germs
2. Explanation:
- Tetanus is caused by the bacterium Clostridium tetani, which produces a toxin causing muscle stiffness and spasms.
- To prevent tetanus, immunization involves administering a vaccine containing weakened or attenuated forms of the bacteria.
- This exposure to weakened germs helps the body's immune system recognize and remember the pathogen, creating immunity without causing the actual disease.
- The immune response triggered by the weakened germs prepares the body to produce antibodies rapidly upon exposure to the actual tetanus-causing bacteria.
3. Other Options:
a) Preformed antibodies: These are ready-made antibodies that provide immediate but short-term protection. However, they do not stimulate long-lasting immunity like vaccines.
b) Wide spectrum antibiotics: Antibiotics are used to treat bacterial infections but do not provide long-term immunity against future infections.
d) Dead germs: Inactivated or dead germs in vaccines can also trigger an immune response, but weakened germs are more effective in stimulating a strong and long-lasting immunity.
In conclusion, immunization through the administration of weakened germs in vaccines is the most effective way to prevent tetanus by inducing a protective immune response without causing the disease itself.
