What causes passive immunity?

Answer 1

The immunity is having sufficient biological defenses to avoid unwanted biological invasion. There are two types of immunities, the adaptive immunity and the innate immunity. At the same time, the adaptive immunity subdivides into natural and artificial immunity. There are two types of natural immunity, which are passive immunity (primary and secondary) and active immunity.

Passive immunity is the one that the fetus receives during the pregnancy of his mother (primary immunity) and which is then reinforced during lactation (secondary immunity). It is a form of rapid protection of short duration, in which the filtered blood, that passes through the umbilical cord to the fetus, transports antibodies and defenses of the mother. It is therefore important that the mother eats well, rests and stays healthy. But the human body is so perfect that even if the mother is ill, it will take all of the nutrients and defenses to the baby so that it can develop normally.

After the baby is born, it's extremely important that the mother supplement the first breastfeeding (colostrum) because it has a high concentration of immunoglobulin.

Answer 2

Passive immunity is simply "passing" immunity by form of vaccination. A vaccination has a very low or inactive form of the disease. Your body develops immunity because it develops antibodies to fight the disease.

Natural immunity is having an immunity passed from mother to infant (from breast feeding). Specific or acquired immunity is when you become immune to something after you became sick from it. For example, you only get the chicken pox once because your body developed an immunity to it.
