Question

Quizplus · Accepted Answer

Newborns gain their immunity initially from antibodies passed across the placenta from the mother. These antibodies provide temporary protection until the baby's own immune system develops, which occurs gradually over the first year of life. Breast milk can also provide additional antibodies and protect against infections. Early immunizations are important in building long-lasting immunity, but they are not the primary source of immunity for newborns. Contact with viruses and bacteria can also help boost immunity, but it carries the risk of infection and illness. Contact with siblings can introduce the baby to a wider range of germs, but it is not a reliable source of immunity.
