| Study objectives | In infants genetically predisposed to atopy, allergen exposure in infancy plays a critical role in the development of phenotypic manifestations. Allergen avoidance in this period leads to a reduction in the prevalence of asthma, other allergic disorders and/or skin sensitisation. |
