MICROANATOMY

Detailed explanation-1: -During the last 3 months of pregnancy, antibodies from mothers are passed to their unborn babies through the placenta. This type of immunity is called passive immunity because the baby has been given antibodies rather than making them itself.

Detailed explanation-2: -Passive Immunity. Passive immunity is provided when a person is given antibodies to a disease rather than producing them through his or her own immune system. A newborn baby acquires passive immunity from its mother through the placenta.

Detailed explanation-3: -Newborn babies get passive immunity from their mothers through the placenta before they’re born. A mother shares the antibodies that she has with her unborn baby. Each baby’s passive immunity is unique because each mother’s immune system is unique.

Detailed explanation-4: -Maternal antibodies Unborn and newly born babies are protected by antibodies from the maternal immune system. These antibodies are shared in two ways: across the placenta and in breast milk.

Detailed explanation-5: -Mothers convey passive immunity to their newborns through the transplacental transfer of antibodies, hereby providing a shield for the infant from pathogen-mediated diseases (1, 9). The amount of transferred antibodies can differ between individuals and is mainly dependent on maternal antibody concentrations (10, 11).
