Question

A person likely to develop tetanus is immunised by giving

• A. Weakened germs
• B. Pre-formed germs
• C. Dead grems
• D. Wide spectrum antibodies

Answer 1

The correct option is B Pre-formed germs

Tetanus vaccine, also known as tetanus toxoid (TT), is an inactive vaccine used to prevent tetanus. A person likely to develop tetanus is immunised by giving pre-formed antibodies and it produces passive immunity. In passive immunity, the antibodies are produced in some other animals in response to given antigen. These pre-formed antibodies are then injected into the humans at the time of need or emergency.

So, the correct answer is 'Pre-formed germs'.
