The administration of antibodies isolated from one individual or species to another to protect the recipient from a toxin or disease is referred to as passive immunity.
Immunity to a disease is achieved due to the presence of antibodies to the disease in the human system. Antibodies are proteins produced by the body to neutralize or destroy organisms that carry toxins and diseases. Antibodies are disease-specific.
passive is the type of immunity that occurs when a person is given an antibody rather than making it by their immune system. For example, passive immunity occurs when the baby receives the mother's antibodies through the placenta or breast milk.
There are two types of immunity: active immunity and passive immunity. Active immunity occurs when our own immune system is responsible for protecting us from pathogens. Passive immunity occurs when we are protected from pathogens by the immunity of others.
