Immunogenic Reaction

Meaning

An Immunogenic Reaction is a precise physiological response elicited by the adaptive immune system upon exposure to an antigen, which results in the generation of specific antibodies and/or specialized immune cells capable of recognizing and effectively neutralizing that specific foreign substance. This highly specific reaction is the fundamental basis of protective immunity, but in a clinical context, it can also refer to undesirable or adverse responses, such as those triggered by certain medications, supplements, or persistent environmental factors. It represents a specific, adaptive defense mechanism crucial for survival.
