A(n) adaptive immunity exposes a person to a specific antigen preparation in order to trigger a protective specific immune response without the person suffering any effects associated with the pathogen.
<h3>What is
adaptive immunity?</h3>
a type of immunity that arises when a person's immune system reacts to a foreign substance or pathogen, such as after an infection or vaccination. Adaptive immunity involves specialized immune cells and antibodies that hunt for and eliminate foreign invaders and are able to avoid disease in the future by learning what those substances look like and creating a new immune response. Adaptive immunity can last for a short period of time, such as a few weeks or months, or it can last a long time, even for the rest of a person's life.
The adaptive immune system, for instance, provides lifelong immunity against measles in people who have recovered from the disease, but not against other common viruses like those that cause mumps or chickenpox.
