Immunity is the body’s ability to destroy foreign materials and pathogens in order to prevent further infection. This specific response is the result of antibodies which is specific to antigen of pathogen. Types of Immunity and the Immune System. 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.

Passive immunity is that derived from the delivery of pre-formed antibodies into the calf and provide short-term protection. Difference between active and passive immunity. This leads to the production of. It adapts to the type of threat that we are exposed to; it produces lymphocytes and antibodies during second exposure which are specific to pathogens when exposed to the first exposure. The first line of defence in a human body against pathogens is through barriers such as the skin, mucus layers, and saliva. Give a few examples of active and passive immunity. Following are the important difference between active and passive immunity: Difference Between Active And Passive Immunity. Active immunity indicates the formation of antibodies through direct exposure to an antigen. 1. Active immunity is the immune response to a pathogen. Active Vs Passive Immunity: Active immunity commonly involves your body direct response to unknown pathogen. It allows an immune system to recognize a disease which will then trigger our body to fight against it. In Active immunity the antibodies are produced by the body as well as introduction of microbes either any infection induces active immunity it is slow but it takes long time and has no side effects In passive immunity thr antibodies are directly given to yhe body as wellas no introduction of microbes takes place .
