Adaptive immune responses are slow to develop, taking days to weeks after exposure to reach their peak. However, these responses are more specific than innate responses, and also generate immunological memory. These latter features, which provide enhanced protection upon re-infection with the same pathogen, are the basis of:
A) Vaccines
B) Antibiotics
C) Systemic shock
D) Complement activation
E) Phagocytosis

Question

Quizplus · Accepted Answer

Vaccines are developed based on the ability of adaptive immune responses to generate immunological memory, providing enhanced protection upon re-infection with the same pathogen. This is achieved by exposing the immune system to a weakened or inactivated form of the pathogen, which triggers the development of a specific immune response without causing disease.
