They’re one of the most common and deadly allergies in the world, affecting 2% of the population, and there’s no cure – but a new study involving skin patches is showing promising results. Similarly to the only treatment available, which involves taking a peanut powder, the Viaskin patch infuses peanut protein into the skin. The trial saw 244 toddlers from 8 countries undergo the therapy for a year, while 118 received a placebo. After the year, patch-wearers with mild reactions could tolerate consuming up to 4 peanuts, while more sensitive sufferers could tolerate one peanut. And patch-wearers who accidentally consumed peanut products during the trial also reported less-severe reactions. The company hopes to bring the patches to market soon – but bad luck to those with an uber peanut allergy… There are still issues with these therapies for those who experience severe reactions like anaphylaxis.
