Infant Immunity Community

Welcome to the Infant Immunity Community hub!

An infant’s immune system is immature and must develop rapidly to evolve and adapt to many foreign challenges in the first few years of life1. This hub is dedicated to supporting healthcare professionals to further develop an understanding of immunity, and how to best support immune development in the infants you are caring for.


I'mmune Aware?

Public interest in immunity is increasing2. As healthcare professionals, you are often the first port of call to handle concerns from new parents of the very young, how prepared do you feel to handle immunity queries?

Here in this hub you will find a variety of resources to help develop your understanding of immunity and infant health. 

I'mmune Informed?

Breastfeeding provides gold standard nutrition to babies, is abundant in factors that protect against infectious disease and can influence immune system development3. The below components of breast milk are often associated with the normal development of a healthy immune system4-6.

Lipids image

Omega-6 Arachidonic Acid (AA) and Omega-3 Docosahexaenoic Acid (DHA) shown to moderate inflammatory responsesand support immune development8

Biotics images

Bioactive compounds produced by beneficial bacteria including short-chain fatty acids, enzymes, peptides and proteins - shown to improve the ability to fight infection by increasing the antibody response to pathogens9 and influencing gut barrier function10

Immunity and the microbiome

70-80% of our immune cells are located in the gut11 and our immune system development is therefore reliant on establishing a balanced microbiome in early life. Amongst other bioactive components and unique factors, the ingestion of prebiotics, probiotics and postbiotics in breastmilk mean that breastfed infants get the best possible start in supporting their immune system development. Breasfed infants are up to five times less prone to developing respiratory tract infections12.
