One of the key and defining characteristics of innate immunity is that it creates stronger, faster, and more specific responses to invaders upon repeated exposure/infection.

Immunity is a defense system we are born with and it protects against all antigens. Innate immunity involves barriers that keep harmful materials from entering your body. Immunity forms the barrier of first line of defense in the immune response.
