Question

The secondary response in antibody-mediated immunity ______.

Options

• is characterized by a slow rise in antibody levels and then a gradual decline

• is an intense response by memory cells to produce antibodies when an antigen is contacted again

• occurs when you first receive a vaccination against some disease

• produces fewer but more responsive antibodies than occur during the primary response

Answer 1

The secondary response in antibody-mediated immunity is an intense response by memory cells to produce antibodies when an antigen is contacted again.

Explanation:

The secondary immune response in antibody-mediated immunity is characterized by a rapid and intense production of antibodies, primarily due to the activation of memory B-cells that were generated during the primary response. This results in a faster and larger amount of antibody production compared to the primary response, which is typically slower and less intense. This principle underlies the effectiveness of booster vaccinations.
