In a secondary immune response, which immunoglobulin is typically most abundant?

Explanation:
In a secondary immune response, memory B cells rapidly re-activate and differentiate into plasma cells that secrete antibodies. These plasma cells predominantly produce IgG, because the response has undergone class switching from IgM and affinity maturation, yielding high-affinity IgG antibodies that circulate in large amounts. This quick, high-affinity IgG response provides strong systemic protection upon re-exposure. IgM is more characteristic of the initial primary response, while IgA is mainly in mucosal secretions, and IgE is linked to allergic and parasitic responses rather than being the dominant systemic antibody after a subsequent encounter.
