Quick Summary

A new study from Australia suggests that one-third of babies diagnosed with a peanut allergy can safely have their diagnosis removed after undergoing a supervised oral food challenge. The research, published in The Journal of Allergy and Clinical Immunology, involved infants who had previously tested positive for a peanut allergy but showed no adverse reaction when exposed to increasing amounts of peanuts under medical supervision. Experts recommend that parents consider having their children retested through this method rather than relying solely on initial testing results or self-administered challenges at home due to safety concerns.

Story summary

Research from the Murdoch Children's Research Institute and the National Allergy Centre of Excellence (NACE) in Australia has found that more than one-third of infants diagnosed with a peanut allergy may actually be able to safely eat peanuts. The study, published in The Journal of Allergy and Clinical Immunology, involved 10 paediatric public hospitals across Australia and found that out of infants who had previously reacted to peanuts and tested positive for the allergy, 34.8% did not react during a supervised oral food challenge. NACE Director Kirsten Perrett noted this number was "surprising" and suggested that current practices relying solely on testing may need reevaluation. The research could lead to changes in how peanut allergies are diagnosed, potentially removing unnecessary allergy diagnoses for many children.

Why this leaning score
This article does not take a side on a contested political question, so it has no leaning score. That is an answer rather than a gap: a match report or a rescue can be warmly or critically written without being left or right, and scoring it anyway is how approval of a subject gets recorded as a political position.
