Describe any two situations where a medical doctor would recommend injection of a pre-formed antibodies (antitoxins) into the body of a patient.

Answer 1

1. When a person is infected with some deadly microbes, a quick immune response is required, such as in the case of tetanus.
2. When a person is bitten by a venomous snake, immediate immunity is needed against the snake venom.

This kind of immunization is called artificial passive immunity. It involves the direct injection of preformed antibodies (or antitoxins) into a patient’s body.

Answer 2

In the following situations, a doctor would advise administering an injection of pre-formed antibodies, often known as antitoxins:

1. Snake Bites: To rapidly neutralize the venom of the snake.
2. Tetanus: Pre-formed antibodies offer instant protection in the event of a tetanus infection. Passive immunization is the term for this kind of immunization. It can be taken therapeutically or preventively and offers instant relief.
