Detailed explanation-1: -The body responds by making its own antibodies. There are two examples of passive naturally acquired immunity: The placental transfer of IgG from mother to fetus during pregnancy that generally lasts 4 to 6 months after birth; and The IgA and IgG found in human colostrum and milk of babies who are nursed.
Detailed explanation-2: -Memory cells can remain in the immune system for long periods – sometimes even up to 75 years. This explains why people develop lifelong protective immunity in certain cases, such as after measles vaccination or smallpox infection.
Detailed explanation-3: -Naturally acquired passive immunity occurs during pregnancy, in which certain antibodies are passed from the maternal blood into the fetal bloodstream in the form of IgG. Antibodies are transferred from one person to another through natural means such as in prenatal and postnatal relationships between mother and child.
