A patient is bitten by a stray dog. The doctor administers an **anti-rabies serum** (containing pre-formed antibodies). This is an example of:
AActive natural immunity
BActive artificial immunity
CPassive natural immunity
DPassive artificial immunity (immediate protection, short-lived)
Answer & Solution
Correct answer: D. Passive artificial immunity (immediate protection, short-lived)
Anti-rabies serum (immunoglobulin) = pre-formed antibodies given by injection ⇒ passive (received ready) and artificial (clinical intervention). Immediate but short-lived. Combined with rabies vaccine (active immunisation) for long-term protection.
