Explainer: Do daycare germs help build immunity?

  • September 1, 2026

So many of us have been struck down with winter illnesses but if you’re a parent to toddlers, it might feel like you’re more nurse than parent right now. 

Which got us thinking about early child daycare .. and whether the endless bugs that often come from there help or hinder kids .. does being exposed to more germs build immunity ahead of school or is that an urban myth parents cling to?

Peter McIntyre is a professor in the University of Otago’s Department of Paediatrics and Child Health, he’s with Jesse for some myth busting.
