Difficulty: HardHealth, Nutrition, and Disease

Administration of an antivenom containing pre-formed neutralizing antibodies confers artificial passive immunity, which provides immediate protection against specific toxins but fails to generate long-term immunological memory because the recipient's own B lymphocytes are not stimulated to produce memory cells.

Answer: Answer

Answer

True. Antivenom provides artificial passive immunity, delivering immediate neutralization via exogenous antibodies without stimulating the host's B lymphocytes to produce lasting memory cells.
Passive immunity involves the direct transfer of pre-formed exogenous antibodies, providing rapid and immediate neutralization of pathogens or toxins without stimulating host B cells to form immunological memory.

Step-by-Step Solution

1
Classify the form of immunity described in the administration of antivenom.
Antivenom consists of pre-formed antibodies harvested from an external source, which defines artificial passive immunity rather than active immunity.
Determining the category of immunity is necessary to evaluate how the host body interacts with the introduced antibodies.
2
Evaluate the mechanism of memory cell generation in relation to passive immunity.
Memory B cells are only generated when the host's naive B cells encounter an antigen, undergo clonal selection, and differentiate during an active immune response.
Directly introducing pre-formed antibodies clears the target antigen without activating the recipient's adaptive immune response machinery.
3
Assess the overall validity of the stem statement.
The statement correctly links passive immunity to immediate protection and accurately identifies the absence of long-term memory formation.
Both clauses in the compound statement are scientifically accurate.

Key Concept

Mechanistic distinction between active immunity and passive immunity regarding antibody origin and immunological memory formation.
