Natural immunity occurs through contact with a disease. There are two types of natural immunity. Actively acquired and passively acquired.

Actively acquired - When the body has already experience an infection by that pathogen

Passively acquired - Antibodies pass across placenta providing a newborn baby with immunity against disease. Antibodies are also present in breatsmilk.

Artificial immunity develops through delibereate action such as vaccine. There are two types: Actively acquired and passively acquired

Actively acquired - This is by vaccination at a suitable time in the person's life, not when they are infected. eg TB vaccine

Passively acquired - The vaccine contains ready-made antibodies which provide immediate relief by destroying the antigens. This is given when the person has been infected with the antigen and has no preivous immunity eg tetanus

Natural immunity is dispersed by the immune system in the body. It sends white blood cells out to "fight" the enemy bacteria or germs. Artificial acquired immunity is given by a doctor, usually through a needle, to disperse special kinds of immunities depending on the sickness.
