Significance of Acquired immunity
Acquired immunity is the body's specific immune response developed over time after exposure to pathogens like bacteria and viruses or through vaccination. It includes the production of antibodies and activation of lymphocytes to provide resistance against these specific foreign bodies. This immunity can vary in effectiveness based on factors such as stress and health conditions, and it distinguishes itself from innate immunity by requiring prior exposure to develop. Acquired immunity plays a crucial role in protecting against reinfections.

The concept of Acquired immunity in scientific sources
Acquired immunity is an immune response that evolves with exposure to pathogens or antigens, distinguishing it from innate immunity. It provides targeted defense against specific pathogens through previous infections or vaccinations.

(1) Acquired immunity is a component of the host defense mechanisms against pathogenic microorganisms, which, along with innate immunity, work together.[1] (2) Acquired immunity is impaired by CDTs due to inhibiting B- and T-cell proliferation and survival, which is a function.[2] (3) A specific immune response that develops over time as the body is exposed to pathogens, including mycobacteria.[3]
