Naturally acquired passive immunity can be provided during pregnancy, and through breastfeeding. [4] In humans, maternal antibodies (MatAb) are passed through the placenta to the fetus by an FcRn receptor on placental cells. This occurs predominately during the third trimester of pregnancy, and thus is often reduced in babies born prematurely.
Human milk immunity is the protection provided to the immune system of an infant via the biologically active components in human milk. Human milk was previously thought to only provide passive immunity primarily through Secretory IgA , but advances in technology have led to the identification of various immune-modulating components.
It’s one of the first major parental decisions: breastfeeding vs. bottle feeding. And it doesn’t need to be either/or – many women do some of both.
Here's what the data says about the breastfeeding vs. formula feeding debate. Rebecca Corey. August 24, 2022 at 11:04 AM. Emily Oster breaks down the data comparing breastfeeding and formula feeding.

Females have a three times higher prevalence than men. LP is characterized by T lymphocytes infiltration of the lower levels of epithelium, where they damage basal cells and cause apoptosis. The fetal microchimerism may trigger a fetus versus host reaction and therefore may play a role in the pathogenesis of autoimmune diseases including LP. [42]
Initially, a newborn relies heavily on passive immunity transferred from the mother, primarily through the placenta and breastfeeding. As breastfeeding frequency declines, immune protection gradually wanes, making the child more vulnerable and increasingly reliant on their developing immune system.
Here’s a look back at some of the highs and lows in formula and breastfeeding in U.S. history — and the societal shaming around them. Late 19th century: "Treat the baby like a machine"
