Global Prevention of Asthma in Children Study

This study is looking at whether a probiotic treatment — a mixture of healthy bacteria given by mouth — can help prevent asthma from developing in young children who have eczema and food allergies. These children are at higher risk of going on to develop asthma. The probiotic is designed to be taken daily and may help train the immune system in a way that reduces the chance of developing airway problems later on.
