Difference: Passive Immunity involves an individual containing antibodies that were not produced by that individual (i.e comes from an external source). Antibodies are produced by the body against the antigen. Passive immunity does rapid-action as the performed antibodies are injected into the body. Subscribe Newsletter. The active immunity requires a longer time to develop as the body itself produces the antibodies. Eg: Skin is a physical barrier as well as chemical and biological barrier as it produces antimicrobial proteins; Surface lining of the respiratory system has cilia for preventing pathogens and building up of microorganisms; Stomach release strong acids with low pH and kills microorganisms that we accidentally ingest while eating; tears also is an example of barrier immunity as it protects our eyes from dust and pathogens. Active immunity is happens due to the contact of lymphocytes with pathoges (or simply their antigens), which triggers the specific immune response and immunological memory is produced (T-Memory cells created).This response is slow and can take up to a couple days, whilst its effects are long lasting.The final products of the immunity are antibodies and T-Memory cells. Active immunity- when you get a disease from another person or when you get vaccine of inactive version Passive- immunity- occurs from mom to baby from breast milk or when a person receives injection actively portion of disease.

Host itself produces antibodies to provide immunity. Effective Time: The active immunity can lose for a longer time as long as the whole life. It prevents or limits an infection; when our immunity or immune system recognizes pathogens, it addresses a problem. 3. Antibodies are obtained from another source. A baby receiving antibodies from her mother’s breast milk and injection of antisera are examples of passive immunity. When a microorganism is successful in crossing barrier immunity, innate immunity is activated. A prominent difference between active and passive immunity is that active immunity is developed due to the production of antibodies in one’s own body, while passive immunity is developed by antibodies that are produced outside and then introduced into the body.
