PATHOLOGY

Detailed explanation-1: -A newborn baby acquires passive immunity from its mother through the placenta. People can also get passive immunity through antibody-containing blood products such as immune globulin, which may be given when immediate protection from a specific disease is needed.

Detailed explanation-2: -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-3: -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-4: -Passive immunity. Each baby’s passive immunity is unique because each mother’s immune system is unique. The exact kinds and amounts of antibodies in a baby’s blood are a reflection of its mother’s levels at birth. These differences can impact how long passive immunity lasts.
