Detailed explanation-5: -Passive immunity is the direct transfer or administration of antibodies to a non-immune person. Examples are: natural transfer of maternal antibodies across the placenta to the fetus during the 2nd half of pregnancy-this helps to protect the newborn against certain infections for a short time after birth.

Detailed explanation-6: -Acquired immunity may be either natural or artificial in nature. Both natural and artificial immunity have passive and active components. Active immunity results from an infection or an immunization, while passive immunity comes from naturally or artificially gaining antibodies.

Detailed explanation-7: -What is an example of active and passive immunity? An example of active immunity is through vaccinations, and passive immunity is through the placenta.
