The human immunodeficiency is divided into two types:
Congenital: it is incorporated genetically and is transmitted hereditarily by generations.
The active group includes immunity, which has arisen after the transferred illness or vaccination.
The passive group includes immunity, obtained with the mother colostrum, intrauterine method or introduction of antibodies into the body.
The immune system of the child begins to develop even in the mother's womb for a period of 5-6 weeks, which is promoted by stem cells. After birth, the baby receives a large number of antibodies with the colostrum of the mother, so for the first time the body is almost invulnerable. All the time, until the baby sucks the breast and gets protection from the mother, his immune system develops.
The child has low immunity for many reasons. His mother, being pregnant, could not pay proper attention to nutrition and replenishment of the body with vitamins, as a result of which the embryo lacked useful substances for the development of a strong immune system.
