Immune System
This category is for questions about how our bodies identify and fight off disease, infection or pathogens through specialized cells, tissues and organs. The system that does this is called the immune system. It produces antibodies which recognize intruders and neutralizes potentially pathogenic organisms or substances.

How can antibodies be transferred from a woman to a fetus and a baby?
As found in Wikipedia
Maternal passive immunity is a type of naturally acquired passive immunity, and refers to antibody-mediated immunity conveyed to a fetus by its mother during pregnancy. Maternal antibodies (MatAb) are passed through the placenta to the fetus by an FcRn receptor on placental cells. This occurs around the third month of gestation.[2] Immunoglobulin G is the only antibody isotype that can pass through the placenta.[2] Immunization is often required shortly following birth to prevent diseases such as tuberculosis, hepatitis B, polio, and pertussis, however, maternal antibodies can inhibit the induction of protective vaccine responses throughout the first year of life. This effect is usually overcome by secondary responses to booster immunization.[3]
Passive immunity is also provided through the transfer of IgA antibodies found in breast milk that are transferred to the gut of the infant, protecting against bacterial infections, until the newborn can synthesize its own antibodies.[4]
The Maternal Antibodies transferred have a half-life of approximately 14 days, and thus only have an effect for the first months.
Soap and water provide a medium in which dirt is lifted from the skin and is mixed within the medium created by the soap and water. As the soap and water are rinsed off the skin, the dirt is carried away as well.

How does a fetus obtain preformed antibodies?
A fetus will start producing IgM antibodies about 20 weeks into the pregnancy. The only antibody the fetus receives from it's mother is IgG which the baby will not start producing on its own until a few months after birth.
What help the immune system work properly?

What are B lymphocyte deficiencies?
If there is an abnormality in either the development or function of B lymphocytes, the ability to make antibodies will be impaired. This allows the body to be susceptible to recurrent infections.
