18 Apr 2019 --- Oral immunotherapy (OIT) is a safe method for treating peanut allergies in children as young as nine-months to five-years of age, according to a new study led by scientists and pediatric allergists at the University of British Columbia and BC Children’s Hospital, Canada. The study examined the cases of 270 children from across Canada who were given OIT for peanut allergies between April 2017 and November 2018, finding that the majority were able to build tolerance to the allergen. Data from the research was published this week in the Journal of Allergy and Clinical Immunology: In Practice.
