A condition of immunity that results when a person has a disease, builds antibodies against the disease, and recovers from the disease.
The immunity from disease which a newborn baby has from birth and which is inherited or acquired in the uterus or from the mother’s milk.
Stage of being innately resistant or insusceptible to a particular disease; also called innate immunity.
Immunity that is genetically determined in specific species, populations, or families. Some pathogens cannot infect certain species because the cells are not suitable environments (e.g., the measles virus cannot reproduce in canine cells; therefore, dogs have natural immunity to measles).
Immunity that is partly inherited and partly developed through healthy living.
Innate immunity refers to a form of defense against diseases exhibited by a species that has not been previously sensitized to the specific disease, either by infection or vaccination.
The processes underlying natural immunity are not yet comprehensively grasped. However, it is distinct from acquired immunity, as it is not thought to be activated by specific antigens that trigger immune responses. Natural immunity, also referred to as innate immunity, is inherent and exists from birth, being passed down through inheritance.
