immune responses
Biological defense reactions
Immune responses are the body's reactions to foreign substances, pathogens, or abnormal cells.
The immune system detects threats and mounts defenses—producing antibodies, activating specialized cells, or triggering inflammation.
The vaccine stimulates an immune response without causing disease.
Responses can be innate (immediate, general) or adaptive (slower, targeted to specific invaders).
An overactive immune response causes allergies and autoimmune disorders.
