A person likely to develop tetanus is immunized administering
A. Dead germs
B. Performed antibiotics
C. Wide spectrum antibiotics
D. Weakened germs

Hint: Tetanus is a serious bacterial endotoxin that affects our nervous system, which leads to painful muscle spasms particularly of our jaw and neck muscles. Tetanus can even interfere with breathing and may eventually lead to the death of a person. It is commonly known as “lockjaw”.

Complete answer:
Tetanus is an infection caused by bacterium called Clostridium tetani. When the bacteria enter the body, they produce a poison (toxin) that further causes painful muscle contractions. Another name for tetanus is “lockjaw”. It mainly causes a person’s neck and jaw muscles to lock, making it difficult for the person to open the mouth or swallow.

CDC recommends vaccines for each and every person that includes infants, children, teens, and adults to prevent tetanus. Tetanus vaccine is also known as tetanus toxoid (TT). It is an inactive vaccine which is used to prevent serious disease of tetanus. A person who is likely to develop tetanus is immunised by giving pre-formed antibodies and these antibodies produce passive immunity.

In this passive immunity, the antibodies are produced in some other animals in response to a given antigen. These pre-formed antibodies are then injected into humans at the time of need or in case of any emergency. Antibodies are specialized proteins that play an important role in the immune response of the body.

Hence, the correct answer is option B.

Note: Signs and symptoms of tetanus include:
1. Spasms and Stiffness in jaw muscles.
2. Stiffness in the neck muscle.
3. Difficulty in swallowing.
4. Stiffness of abdominal muscles.
5. Painful body spasms.
