what is artificial immunity

The immune response is broken down into innate immunity, which an organism is born with, and adaptive immunity, which an organism acquires following disease exposure.

Are allergies innate or adaptive?

Both the innate and adaptive immune systems play a role in allergy, which occurs as a result of sensitisation to harmless substances in the environmental (e.g. dust and pollen), and hypersensitive reactions upon subsequent exposure to these particles.

Why do we need adaptive immunity?

The function of adaptive immune responses is to destroy invading pathogens and any toxic molecules they produce. Because these responses are destructive, it is crucial that they be made only in response to molecules that are foreign to the host and not to the molecules of the host itself.

What is adaptive immunity simple?

Adaptive immunity involves specialized immune cells and antibodies that attack and destroy foreign invaders and are able to prevent disease in the future by remembering what those substances look like and mounting a new immune response.
