Dec 8, 2009 · The adaptive immune system (AIS) is fascinating to both scientists and laymen: we have a specific yet incredibly diverse system that can fight myriad pathogens and has a 'memory' — the basis of...
Mar 13, 2024 · Adaptive immunity is often sub-divided into two major types acording to how the immunity was introduced. Naturally acquired immunity occurs through non-deliberate contact with a disease causing agent, whereas artificially acquired immunity develops through deliberate actions such as vaccination.
Sep 12, 2018 · Beyond structural and chemical barriers to pathogens, the immune system has two fundamental lines of defense: innate immunity and adaptive immunity. Innate immunity is the first immunological mechanism for fighting against an intruding pathogen.

After the initial infection, the body develops immune memory for the virus, conferring immunity against the disease so if they encounter it again, they are able to fight it off swiftly and don’t go on to develop clinical disease again.
