IMMUNOLOGY

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. 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-3: -A type of immunity that occurs when a person is given antibodies rather than making them through his or her own immune system. For example, passive immunity occurs when a baby receives a mother’s antibodies through the placenta or breast milk.

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: -Passive immunity provides immediate but short-lived protection, lasting several weeks up to 3 or 4 months. Passive immunity can occur naturally, when maternal antibodies are transferred to the fetus through the placenta or from breast milk to the gut of the infant.

Detailed explanation-6: -A mother’s antibodies are shared with their baby through the placenta during the third trimester (last 3 months) of pregnancy. The mother’s antibodies help protect the baby from illnesses when the baby is born. The type of antibodies passed from mother to baby depends on the mother’s own level of immunity.

Detailed explanation-7: -There are two types of passive immunity: artificial and natural.
