Innate immunity/inborn/genetic/heritable: Nonspecific host defenses that exist prior to exposure to an antigen and involve anatomic, physiologic, endocytic and phagocytic and inflammatory mechanisms. Read more>>
Adaptive immunity/acquired/specific: Host defenses that are mediated by B and T cells following exposure to antigen and that exhibit specificity, diversity, memory and self/non-self-recognition. Read more>>
Difference Between: Innate Immunity vs Adaptive Immunity
Innate Immunity vs Adaptive Immunity
Acquired (Adaptive) Immunity
Present from birth itself.
Develops during life time
The immunity remains throughout life.
Can be short lived or lifelong.
Contact or exposure with pathogen or its antigen is not essential.
Contact with pathogen or its antigen is essential.
Innate immunity is inheritable.
Acquired immunity cannot be passed to the next generation except for a brief period to neonates.
It protects the individuals from contraction of diseases of other organisms.
It protects the individuals from pathogens present on other members of the same species.
