How do newborns get their immune protection from the mother?
Human BiologyImmunology
Quick Answer
Before birth and after birth, babies receive antibodies from the mother that provide temporary protection. These antibodies help shield the newborn while its own immune system matures.
The Full Story
During pregnancy, maternal antibodies cross the placenta into the fetus, especially in the third trimester. After birth, breast milk—particularly colostrum in the first days—contains additional antibodies and immune factors. This passive immunity does not last forever, but it is crucial in the early months of life. Over time, the baby’s own immune system develops responses to infections and vaccines.
Key Facts
1.Maternal antibodies cross the placenta during pregnancy
2.Colostrum is rich in immune factors
