Immunity refers to the state of having sufficient biological defenses to avoid infection, disease, or other unwanted biological invasion. It involves both specific and nonspecific components. The specific components, such as antibodies and sensitized T-cells, target particular pathogens, whereas nonspecific defenses provide general protection against any pathogens. Immunity can be naturally acquired through exposure to pathogens or artificially induced through vaccination.
