Why is innate immunity considered nonspecific?

Innate immunity is nonspecific because it uses general, broad defenses that apply to many different microbes rather than a tailored, pathogen-specific response. It relies on pattern-recognition receptors to detect common features of pathogens and launches rapid, standardized actions such as inflammation, phagocytosis, and antimicrobial substances. It does not produce antibodies or rely on highly specialized receptors for each pathogen, and it does not require prior exposure to work. This is why the idea that it doesn’t distinguish one threat from another best captures the nonspecific nature of innate defenses. In contrast, antibody production, targeting specific threats, and dependence on prior exposure are hallmarks of the adaptive immune system.
