NNIW 100 Interviews: Giles Major

There is currently no universally accepted definition of a healthy microbiome. Many of the terms and parameters we commonly use are more applicable to adult health and may not be as relevant to early life. When considering the development of a healthy microbiome, we should shift our focus away from measures like diversity and the species associated with healthy aging. Instead, we should concentrate on what's critical during the first months, the initial 100 days, and the first thousand days of life. In particular, it's crucial to understand the trajectory of microbiome development and the rate at which we expect changes to occur during this critical period."
