Point of distinction

Innate immunity

Acquired      immunity
Definition Immunity with which an individual is born Immunity which is gained later in life
Immunity Provided by Anatomical barrier

Physicochemical barrier

Phagocytosis

Inflammation

 Antibody

Certain T-cells
Specificity Not specific Specific
Diversity Limited diversity High diversity
Duration of immunity From birth to death Not life long
Mechanism of immunity Almost same in all individuals Not same, diverse type
Self/non-self recognition No Yes
Immunological memory No Yes
Line of defense First line of defense Provide defense only if innate immunity is compromised
Response rate Fast Slow (1-2 week for antibody production)
Potency Low or limited High potency
Inheritance Inherited from parents Not inherited, Acquired later in life
Complement activation Alternative and lectin pathway Classic pathway
Protection against Microorganisms Microorganism, toxins, chemicals, antigens
Allergic reaction None Immediate and delayed hypersensitivity reaction
