Treatment for adults would be nice, but I take solace from the future. At least more kids won't need to grow up with an extreme concern. Meantime grown-ups keep carrying the epipen.
It is not well known but this also works for adults too. I’m 28 and recently completed oral immunotherapy therapy for my extremely severe peanut allergy. I used to go anaphylactic from single milligram exposure and now I’m eating multiple peanuts a day. As an adult you have to go slower and be more careful but absolutely can be done and is life changing.
