Question

Quizplus · Accepted Answer

The early switch to IgE during a primary immune response often results in IgE molecules that have a lower affinity for their specific antigen. This is because the switch occurs before the B cell has undergone extensive somatic hypermutation and affinity maturation processes in the germinal center, which are necessary for producing high-affinity antibodies.
