Innate immunity is present at birth.

Explanation:

The immune system is divided into two categories such as innate immunity and adaptive immunity. The innate immunity is present in an individual during birth. It does not depend on prior contact with microorganisms or immunization. It is present at birth and changes throughout the life of the individual. There are different barriers of innate immunity such as skin, mucous, lysozymes (present in the tears). This type of response is rapid and not specific. It has no memory. The cells of innate immunity are the phagocytic cell, dendritic cells.
