What is the difference between natural and artificial active immunity?
Figure: Immunity: Natural immunity occurs through contact with a disease causing agent, when the contact was not deliberate, where as artificial immunity develops only through deliberate actions of exposure.
What is the difference between natural immunity and acquired immunity?
Natural immunity is acquired from exposure to the disease organism through infection with the actual disease. Vaccine-induced immunity is acquired through the introduction of a killed or weakened form of the disease organism through vaccination.
