The grаph illustrаtes аntibоdy cоncentratiоn over time following two exposures to the same antigen. The primary response shows an initial IgM peak followed by a modest IgG increase. The secondary response demonstrates a rapid and significantly higher IgG spike. Using this information, write a detailed essay that: Describes why the secondary exposure results in a faster, stronger IgG response, including the role of memory B cells and helper T cells. Connects the graph to the biological principle underlying vaccination and booster doses. Predicts what would happen to the IgG curve in an immunocompromised individual with impaired B-cell function. Your explanation should integrate terminology such as plasma cells, cytokine signaling, and immunologic memory, and demonstrate clear cause-and-effect reasoning at the cellular level.
