Available now with access through 4/17/2025

Course description
The immune system is fascinating – from the time an individual is born, immune cells are sending messages to teach the body which foreign molecules are benign, and which are a threat. It does take time for a newborn infant’s immune system to function properly; however, evolution has accounted for this. Human milk provides essential bioactive and immune components that support the infant’s developing immune system so that appropriate responses can occur. In this course, you will learn about the basics of the immune system and how it develops, the immunological components in human milk, how breastfeeding is impacts the infant microbiome, and more.

Learners say 

This course was great in fully understanding how the immune system is as a foundation when baby is born and how uniquely it is developed. I enjoyed learning more about how mom & baby's immune systems interact and build.
