The adaptive immune response is mediated by lymphocytes. Its hallmarks are a high specificity for distinct antigens and an immunological memory.
Specific immune response
Adaptive immune reaction
An adaptive immune response is stimulated by exposure to infectious agents or their products. It is mediated by T and B lymphocytes
. Through their differentiation, an immunological memory is established. Repeated exposure to the same antigen
will then lead to a faster and more vigorous immune response
. This is also the principle behind vaccinations.
