What is the typical immune response for most allergies?

The typical immune response for most allergies is categorized as mild. Allergies occur when the immune system reacts to a substance (allergen) that it mistakenly identifies as harmful. In the case of common allergens such as pollen, dust mites, or pet dander, the immune response usually involves the production of antibodies, particularly Immunoglobulin E (IgE), and the release of histamines.

While the response may cause discomfort, such as sneezing, itching, or mild swelling, it is generally not life-threatening for the majority of people and is characterized as a mild response. In some scenarios, individuals can experience more significant effects depending on their sensitivity to the allergen, but these cases are less common.

The terminology used in the other options suggests higher levels of severity or exaggeration than what is typically seen in allergies. For most individuals, the immune response is indeed mild, making it the appropriate answer.
