During a Successful Secondary Immune Response

Question

During a successful secondary immune response:
A) the inductive period will be longer than it was during a primary response.
B) greatly increased levels of IgM are produced.
C) long-lived plasma cells immediately begin secreting antibody.
D) the number of pathogens should remain below the threshold of disease.
E) there will be a stronger cell-mediated response, but a less vigorous humoral response.

Accepted Answer

During a successful secondary immune response, the immune system responds more rapidly and effectively than it did during the primary response, thanks to the memory cells produced during the first exposure. This means that the number of pathogens is kept below the threshold that would cause disease, as the immune system can quickly eliminate or control the infection.
