Question

After an initial exposure to antigen, which of the following is not a typical time period for the generation of a secondary immune response?

A) Days to weeks
B) Weeks to months
C) Months to years
D) Years to decades

Answer 1

The generation of a secondary immune response typically occurs within a shorter time period than the primary response, with a reduced lag period. IgG production is significantly higher in the secondary response.

Step-by-step explanation:

The correct answer is D) Years to decades. After an initial exposure to antigen, the generation of a secondary immune response typically occurs within a shorter time period than the primary response. The secondary response is faster and more forceful, with a lag period reduced to a few days. During the secondary response, the production of IgG is significantly higher than in the primary response, and antibodies produced are more effective and bind with higher affinity to the targeted epitopes.
