Official Immunity Law and Legal Definition. Official immunity is a discretionary immunity from personal liability that is granted to public officers for tortious acts and omissions. It is a personal immunity accorded to a public official from liability to anyone injured by actions that are the consequence of exerting official authority.
Active and Passive Immunity. Naturally acquired active immunity occurs when the person is exposed to a live pathogen, develops the disease, and becomes immune as a result of the primary immune response. Artificially acquired active immunity can be induced by a vaccine, a substance that contains the antigen. vaccine stimulates a primary response against the antigen without causing symptoms of the disease (see vaccination). Artificially acquired passive immunity is a short-term immunization by the injection of antibodies, such as gamma globulin, that are not produced by the recipient's cells.
