15.Active immunity involves your bodies direct response to an unknown pathogen. This response is the production of antibodies specific to the antigen of a particular pathogen. This type of immunity is not immediate as it takes time to have create enough of the correct antibodies to fight the pathogen. However, the response lasts for a long period of time and in some cases, where antibodies remain in the body as memory cells, immunity to the specific pathogen may be life long. Conversely, passive immunity is an immune response which involves antibodies obtained from outside the body. An example of this is the antibodies a mother passes to her infant through her breastmilk. Immunity to the pathogens which these antibodies are specific to is therefore immediate, as no time is needed to create them. However, this immunity is not long term and may only last a few days
