Original Khojo Papers practice question — not from a past board paper.
Answer
Innate immunity is present from birth and is non-specific, comprising barriers such as the skin, phagocytic cells and inflammation. Acquired immunity is developed during life, is specific to a pathogen and has memory. Active immunity is produced when the body makes its own antibodies after infection or vaccination and is long-lasting; passive immunity is the transfer of ready-made antibodies, which acts at once but does not last.
No citable source has been recorded for this record. Treat it as practice material, not as fact.
