Are Acquired Immunity and Adaptive Immunity the Same?

Adaptive immunity is also referred to as acquired immunity or specific immunity and is only found in vertebrates. The adaptive immune response is specific to the pathogen presented. The adaptive immune response is meant to attack non-self pathogens but can sometimes make errors and attack itself.

Why the adaptive immune response is also called acquired immunity?

This acquired response is called "adaptive" because it prepares the body's immune system for future challenges (though it can actually also be maladaptive when it results in allergies or autoimmunity). The system is highly adaptable because of two factors.

How Adaptive immunity is acquired?

Adaptive immunity is an immunity that occurs after exposure to an antigen either from a pathogen or a vaccination. This part of the immune system is activated when the innate immune response is insufficient to control an infection.
