For example, antibodies passed from the mother to the baby before birth confer passive. Passive Immunity in Bacteria. See all full list on thoughtco.


A different type of immunity , called passive immunity , when a person is given someone else’s antibodies. When these antibodies are introduced into the person’s body, the “loaned” antibodies help prevent or fight certain infectious diseases. The protection offered by passive immunization is short-live. The transfer of maternal tetanus antibody (mainly IgG).

The passive immunity is the immunity conferred to an individual by the transfer of serum or lymphocytes from a specifically immunized individual.


It is of two types: natural or active and artificial or passive. Active immunity is produced by clonal selection and expansion. A type of immunity acquired by the transfer of antibody from one individual to another, such as from mother to offspring.


There are two ways to acquire passive immunity : (1) naturally acquired passive immunity and (2) artificially acquired passive immunity. Innate immunity provides first-line defense against pathogens through physical and chemical barriers such as skin, mucous layers, and saliva. The active immunity requires a longer time to develop as the antibodies are produced by.
