Newborns Gain Their Immunity Initially From

Question

Newborns gain their immunity initially from
A) early immunizations during routine neo-natal check-ups.
B) contact with viruses and bacteria.
C) antibodies passed across the placenta from the mother.
D) contact with siblings.
E) breast milk.

Accepted Answer

Newborns gain their immunity through antibodies that pass from the mother's bloodstream to the fetus through the placenta. This is known as passive immunity and can provide protection for the first few months of life. Breast milk also contains antibodies and can further help to protect the newborn from infections. Immunizations do not typically begin until the baby is at least 2 months old. Contact with viruses and bacteria can help to build the baby's immune system, but should be monitored to avoid serious infections. Contact with siblings can also expose the baby to viruses and bacteria, but again, caution should be taken to minimize the risk of serious illness.
