Question

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

Hint:

Pre-formed antibodies (antitoxins) provide immediate protection against specific toxins or venoms, as they neutralize harmful substances before the body has a chance to produce its own immune response.

Answer 1

Situations prompting a medical doctor to recommend pre-formed antibody (antitoxin) injections:
1. Tetanus Infection: 
- Tetanus antitoxin injection is advised for individuals injured by contaminated objects or exposed to tetanus-causing bacteria. Because the body has not yet produced antibodies against the toxin, immediate administration of pre-formed antibodies neutralizes the tetanus toxin, thereby preventing infection.
2. Snakebite (Venom): 
- In cases of venomous snakebites, a doctor may administer snake antivenom, which comprises pre-formed antibodies targeting the snake's venom. This intervention neutralizes the venom before systemic spread and severe bodily damage can occur.
